RE: Text within Equation
Something like [cid:image001.png@01DAE719.6D9682B0] ?? I have written the text (“Channel redundancy”, etc. as text – start text mode by \text + Space, and use arrow to step out of text mode. I have created the space after math expressions and text (e.g., “bits/symbol”) using the math space operation (\qquad + Space). If you want to align the text strings to the right, the simplest is probably to but the math expression into a table.

Option for displaying equation labels less obstrusively?
Hello! As it is currently implemented, equation labels are displayed as part of the equation number in LyX's editor. Sadly, for longer, semantically meaningful label names (e.g. "eq:maxwell-equations-in-vacuum"), this throws off the formatting in the editor buffer: Instead of centering the equation, the combination of label and equation is centered. A similar problem occurs, when left-aligned equations with left-aligned numbering are used. Screenshot (if not displayed inline: https://imgur.com/a/Y1rDmgE) Made in full-screen mode with limited text-width. Is there some setting in LyX, that allows getting better alignment, without sacrifizing the ability to use long label names? - Klaus
latex equation copied from MathType generally shows redundant { }
Dear lyx developers and usersI am new to lyx. Before using lyx, I always use Mathtype software to typeset equations which can be downloaded from www.dessci.com/en/products/mathtype/ The equations in mathtype can be copied as latex format.for example, an _expression_ looks like thishttps://pasteboard.co/HpwLYea.pngis copied as latex code as below\left( {\begin{array}{*{20}{c}}{{e^{ - i\phi /2}}}\\{{e^{i\phi /2}}}\end{array}} \right)I then paste this latex code into lyx math mode, however, it shows like thishttps://pasteboard.co/HpwKWg4.pngwith annoying redundant { and } symbolHowever, if you tried any online latex equation editors likehttps://www.codecogs.comhttps://arachnoid.com/latex/etc.You will find the latex code copied from mathtype is perfect with any redundant { }So I think the latex equation interpretation in lyx should be improved. This issue should be solved. Thank you very much! looking forward to your reply.best regards

That is a good idea, and consistent with what JMarc suggested (of
splitting at the cursor). I see there's lots of room for improvement.

Tim, Whenever something like this happens I immediately wonder about whether all the fonts are embedded in the PDF. If I check with Image Viewer (I'm using Linux Mint), I get the reassuring message "All fonts are either standard or embedded", with ten unexceptional Type 1 fonts, all with Embedded subsets. And one Type 3 "No name" font described as Embedded, not Embedded subset. The equations do render correctly with this viewer, and with the Chrome viewer. If I open the downloaded file with Acrobat Reader 9, it renders correctly, but the Type 3 font is described as" F56 Type: Type 3 Encoding: Custom Actual Font: F56 Actual Font Type: Type 3 There is no mention of it being embedded. I don't know where this font is coming from in your document, but it may be the problem. None of the viewers I tried had any problems with correctly displaying your PDF. Les -- L. R. Denham

I assume you are speaking about LyX-produced PDF output, right? My guess is, that the user used a resolution/magnification so small, that the thickness of the lines in = was rounded to 0 by the software. There is no easy cure, some suggestions: * whenever details are missing, magnify the document and see whether they turn up. * use a font with bolder symbols (e.g. newtxmath) * use a larger font size (Document>Settings>Fonts>Base Size) Günter
Re: Bad equation renderings
The equal sign shows up well for me in both Chrome and Safari. I've had good luck with Foxit on Windows; however, I suspect this is can be blamed on it. It might be interesting to force embedding the fonts in the PDF and see if the user can see the equal signs then.

equation numbering scheme. In other words, you want (2.3.3)DELTA consecutive
between (2.3.2) and (2.3.4), rather than having both a (2.3.3) and a
(2.3.3)DELTA.
Create a math macro (Insert > Math > Macro), name it something like \mytag,
and fill the TeX code slot with
\stepcounter{equation}\tag{\theequation\Delta}
and the LyX display slot with ?\Delta?. There's nothing sacred about what
goes in the LyX slot; feel free to change it at will. More about that in a
second.
Then, in any equation you want to flag, just type \mytag in the equation
body. LyX will display ?\Delta? (or whatever you substituted) in the
equation, and will annotate the equation number correctly in the output. If
you leave the LyX portion of the macro empty, LyX will expand the macro
inside the equation. That still works, but it makes for some remarkably ugly
equations in the LyX GUI.

Equation numbering variants
Hi Can someone give me a hint how I could create a different equation numbering variant? Currently all my equations are numbered like: (2.3.2) For some select equations I would like this to change to: (2.3.3)Δ The counting is continuous, some equations just have an additional DELTA at the end. Any help is appreciated. Franci Žižek
Re: how can i set up a shortcut for equation label?
Dear Chen, See in Preferences > Keyboard shortcuts. The action is label-insert and you can define a shortcut of your choice for it. In your case you will find label-copy-as-reference useful too, to later paste the reference.

Bad auto-splitting when switching to equation array
In a math environment (display or environment), you can switch to an EqnArray environment with Ctrl Enter or Shift Enter. If there is already an equation, it will be automatically split into columns on particular symbols, including "=" and a few other operators and arrows. Unfortunately, it passes right over some symbols (such as \coloneqq or \dblcolon). It also splits on the first symbol, so "a = b \Leftrightarrow c = d" will become "a&=&b\Leftrightarrow c=d" rather than "a=b & \Leftrightarrow & c=d", but at least that can be avoided with parentheses. Is there some way to add operators like \coloneqq and \dblcolon to the list of symbols that equations will be split on?

I found another solution:
\usepackage{pgfpages}
\pgfpagesuselayout{resize to}[a4paper,landscape,border shrink=5mm]
although this is not quite as large as I'd like. Maybe I can learn the
pdfpages
options and improve it.
resize equation output
I have the misfortune to be commanded to produce ppt. So I took one of my
equations, in lyx. I chose beamer so I get something that'll look good on a
slide. I put
\beamertemplatenavigationsymbolsempty
so crop will work.
When exported export/pdf(crop), it looks OK, but it's too small. I import to
M$
PPT by opening in acroread and copy file to clipboard.
So I need something that'll resize the pdf (or convince lyx/beamer to output
something bigger in the first place).
I tried the latter without success.
Putting in preamble
\geometry{paper=a4paper}
didn't seem help.
Finally, I found this magic incantation:
gs -sDEVICE=pdfwrite -sPAPERSIZE=a5 -dFIXEDMEDIA -dPDFFitPage -
dCompatibilityLevel=1.4 -o eq1_2.pdf eq1.pdf
Then run through
pdfcrop
Finally, not a bad result (oh, did you want that centered on the slide?)
Any better ideas?

"Equation editor" (was Bounding box for pstricks graphics with LyX)
Hullo Liviu,
I've now tried your "equation editor/picture cropper" at
http://www.lyx.org/trac/ticket/7839 using GSview for postscript and
Acroreader for pdf.
For both template files, EPS.lyx and PDF-cropped.lyx, I had to reduce
the \lyxformat from 416 to 413 for them to be accepted by LyX 2.0.2 on
my system.
For both ps and pdf I tried an equation (Pythagoras' theorem,
a^2+b^2=c^2) and a pstricks graphic (a labelled right-angled triangle).
Postscript: in GSview, the equation is cropped just right. That's neat.
I like it. The triangle however is cropped too severely, so that the
labels for the vertices and two of the sides are largely cropped out of
the picture. The cropping is targeted at the geometric stuff as if the
text stuff isn't there. I used:
\pspicture*(4,3)
%draw the triangle
\pspolygon(.5,.5)(3.5,.5)(.5,2.5)
%draw the right angle
\psline[linewidth=.5pt](.7,.5)(.7,.7)(.5,.7)
%label vertices and sides
\uput{1pt}[0](3.5,.5){A}
\uput{2pt}[90](.5,2.5){B}
\uput{3pt}[180](.5,.5){C}
\uput{2pt}[180](.5,1.5){$a$}
\uput{2pt}[270](2,.5){$b$}
\uput{2pt}[45](2,1.5){$c$}
\endpspicture
in an ERT inset with \usepackage{pstricks} in the preamble of a LyX
document based on the EPS.lyx template.
PDF: Compiling with pdflatex, which I presume is what is intended, I get
an error message in LyX at the cropping stage:
An error occurred while running: pdfcrop "equation.pdf" "tmpfile.out"
Looking in the temporary directory shows the aux, log, tex, and
tex.dep-pdf files. The log file claims "Output written on equation.pdf"
but there is no equation.pdf there.

Put the table in a table float, right click the handle of the float, pick Settings, and check "Rotate sideways". That was my problem: I kept looking for the settings by clicking on the table itself or the table tools that display when the cursor is within the table. I don't think that in all the years I've been using LyX that I ever right-clicked on the grey square reading 'Figure' or 'Table'. How interesting! I do the above, save the document, and look at the dvi preview. It's not rotated but in the upper right corner of the page and off both margins. But ... A-ha! It is rotated in the pdflatex output. It occurred to me that sometimes the dvi preview does not display properly while the compiled output does. Thanks for the lesson, Rich

I was copying them to the table cells. I can retype them as multiline and see if that works. It should. I looked to see if I could convert from inline to multiline but did not see how to do this. 2.

See? It's that sort of a day. Those should be \begin{... and not

I've given up and re-did the table as non-floating. I cannot use the
captionabove environment because LyX tells me that makes no sense. That
response makes no sense to me.
I've not been able to use the rotate or lscape packages to turn this one
wide table 90 degrees. I would appreciate learning how to place a float
table within \being{sidewaystable} and \end{sidewaystable}, or
\being{landscape} and \end{landscape}.
It's been a frustrating couple of hours reading the appropriate sections
of TLC2 and not getting it to work. Haven't had such recalcitrant issues
with LyX for many years.

Long Math Equation in Table Column
I've looked in TLC2 without finding the solution to splitting an inline equation when it's in a table column. I have two long equations in a 2-column table and they make the table much too wide; it extends past the text width on the right. Making the font a smaller size is one solution, but I'd prefer to have the equation span multiple lines within a single table cell. Is there a way to do this? TIA, Rich

Also, are you perhaps using a customized UI file that might be remapping Alt+M+N? The only other thing that I can think of is to type Alt+M+N in different parts of a document (text area, heading, title, ...) until you find out what LyX thinks it maps to (assuming LyX thinks it maps to a different command).

Cross-reference in equation in lyx 2
Hello, In LyX pre-2.0 I was able to put a cross-reference to an equation inside a formula, so that it would look something like in this image: http://www.latex-community.org/forum/download/file.php?id=4130 If I try to do this in LyX 2.0 the reference ends up immediately above the formula, but outside of it. Does anyone know how to put cross-references in formulas in 2.0? Best Regards, David

This gets me exactly what I had in pure LaTeX, which makes sense. The problem really is in the default alignments that AMS-LaTeX uses here. I don't know offhand what the rules are supposed to be, but the problem is that some of the columns are right-justified, and others are left-justified. I'm sure that the algorithms are available somewhere. You placing the = in the first column, rather than in a column by itself, changed the count of columns, and thus the justification. The justification is different in LyX than it is in the output, which might be something to worry about in the future. -- David L.

Re: Equation annotations in a multiline equation
Thanks, after pasting in the text and then examining it I was able to
figure out the correct approach. It appears my earlier alignment
difficulty stemmed from placing the equals sign in its own column. Now
I create a four-column structure in the align environment, with
equation= in the first column, equation in the second column, nothing
in the third column, and the annotation in the last column. This gets
me exactly what I had in pure LaTeX, which makes sense.
