Hi,

in theory the titletoc package should provide for this. I created an  
example file, unfortunately there are artifacts in the lists that I do not  
know how to get rid of.

Very nice and very cool indeed! Thanks a lot Andrew! This seems to be a

I've written a LaTeX package called calculyx which numerically 
evaluates mathematical expressions in LyX before one's eyes using 
instant preview.  It is written in the expl3 language of LaTeX3 but is 
used just like any other LaTeX package. There is a link at 
http://wiki.lyx.org/Examples/Calculyx to a zipped archive currently in 
a Dropbox folder, and a screenshot (.png format) of a one-page LaTeX 
document and the resulting pdf with a few example calculations at 
https://www.dropbox.com/s/7djkyjs44bpraol/Screenshot%202014-11-24%2013.52.07.png?dl=0. 
The LaTeX may look complicated, but using LyX, all that is as ever 
hidden. One simply enters expressions in the LyX math editor as usual.


Calculyx requires the three LaTeX3 bundles l3kernel,  l3packages and 
l3experimental. Because a main routine uses a  command that was 
introduced to l3kernel on 18 July 2014, the version of l3kernel must 
be later than this. The calculational engine for calculyx is the 
floating point module l3fp in l3kernel.


I have tried to ensure as much as possible that calculyx reads 
expressions as mathematicians write them. For instance it will 
digest \sin 3x - 3\sin x + 4\sin^{3} x (for a specified value of x, 
say \pi/6) without parentheses around the arguments and with the 
superscript in the wrong but familiar place. It will digest the 
common arithmetic operators, plus variants like \times and \div, the 
familiar trigonometric and hyperbolic functions and their inverses, 
the exponential and natural logarithm, fractions (\frac, \tfrac), 
square root and \surd, factorials ( using !), binomial coefficients 
(\binom, \tbinom), \gcd, sums and products (\sum, \prod) including 
infinite sums and products, limits (\lim), derivatives (1st and 2nd 
order), including Cartesian 2-d and 3-d Laplacians, and definite 
integrals in one variable. Results are generally presented in the 
form: expression = result. There is also a (multi-column) table 
creating command and another which will iterate a function (for the 
chaos theorists).


The package contains a novelty that I think could be exploited more 
widely. Some calculations are computationally intensive. So as not to 
burden the compilation of the pdf with them, these calculations can be 
parked either in a LyX note or in an inactive branch. Instant 
preview works in both places (with a caveat for LyX notes). The result 
of the calculation can be saved to a LaTeX control sequence. Calculyx 
automatically saves such control sequences to a file. They are then 
available for inserting elsewhere in the document -- even at the 
start, long before the place where the calculation is performed. If 
you are prepared to set up a converter and copier, then the file 
containing the control sequences can be saved in the document 
directory -- or copied to other directories whereby the results of 
those parked calculations are made available to these other 
documents. By this means selected items in LyX notes or inactive 
branches can play a part in compilation to pdf.

Dear Andrew, thanks for the excellent idea. I will be a true believer and

Nevertheless, I have just tried a simple sum and the following error is
presented at compilation time:

Hullo Julio,

My beta tester (there was one) also stumbled over this issue which is 
why I wrote in my introductory spiel:


Calculyx requires the three LaTeX3 bundles l3kernel,  l3packages and 
l3experimental. Because a main routine uses a  command that was 
introduced to l3kernel on 18 July 2014, the version of l3kernel must be

The command that was introduced in July is the one in your error 
message: \clist_reverse:N.
Unless your version of l3kernel is later than 18 July this year, 
calculyx won't work. You will need to download a newer version of l3kernel.


Any calculation that involves variables (n in your test expression) is 
going to meet this command. You could try something involving only 
constants or numbers: e^{\pi}-\pi^{e} perhaps, or 1+1!

Andrew

Yes, I did look at the Sage module, and was daunted. Calculyx is for 
back-of-envelope stuff. Actually it can do some quite complicated 
calculations:


\sum_{k=0}^{\infty}\frac{(-1)^{k}}{2^{k+1}}\sum_{n=0}^{k}(-1)^{n}\binom{k}{n}\frac{1}{(k-n)!}
(a laborious way of calculating 1/e) is about the most complicated I've 
included in the documentation, but you would never use it for serious 
number crunching. LyX Document

Dear Andrew, thanks for the excellent idea. I will be a true believer 
and user once it works smoothly.


Nevertheless, I have just tried a simple sum and the following error 
is presented at compilation time:


! Undefined control sequence.

\clyx_vvlist_process:NN ...ist #1\clist_reverse:N

\l_tmpb_clist \clist_map_i...

l.25 \calculyx{$\sum_{n=1}^{2}n$}


No result of this sum is shown in the preview. Did I do something wrong?

Hullo Julio,

My beta tester (there was one) also stumbled over this issue which is 
why I wrote in my introductory spiel:


"Calculyx requires the three LaTeX3 bundles l3kernel,  l3packages and 
l3experimental. Because a main routine uses a  command that was 
introduced to l3kernel on 18 July 2014, the version of l3kernel must be 
later than this."


The command that was introduced in July is the one in your error 
message: \clist_reverse:N.
Unless your version of l3kernel is later than 18 July this year, 
calculyx won't work. You will need to download a newer version of l3kernel.


Any calculation that involves variables ("n" in your test expression) is 
going to meet this command. You could try something involving only 
constants or numbers: e^{\pi}-\pi^{e} perhaps, or 1+1!


Regards,

Andrew

Yes, I did look at the Sage module, and was daunted. Calculyx is for 
back-of-envelope stuff. Actually it can do some quite complicated 
calculations:


\sum_{k=0}^{\infty}\frac{(-1)^{k}}{2^{k+1}}\sum_{n=0}^{k}(-1)^{n}\binom{k}{n}\frac{1}{(k-n)!}
(a laborious way of calculating 1/e) is about the most complicated I've 
included in the documentation, but you would never use it for serious 
number crunching. LyX Document
