Re: [NTG-context] Simple command with variable number of arguments
Dear Hans,
Here is the file in my desktop.
The reason I didn’t define “sgn” in the function “uppertri” is that it is
inherited from the call of “determinant’.
However, I put “sgn=1” so that the function “uppertri” works independently.
I checked the function “uppertri” and found that it worked fine. Here is a
sample file.
\environment MatrixLuacode
\starttext
\getbuffer[luaMatrix]
\startformula\startalign
\startluacode
local mat = {{0, 2, 4, -4, 1},{0, 0, 2, 3 , 4}, {2, 2, -6, 2, 4 }, {2,0 , -6,
9, 7},{2, 2, -6, 2, 4 },{2, 2, -6, 2, 4 }}
-- local mat = {{1,2,3},{3,4,5},{3,4,5},{3,4,5},{3,4,5}}
context.NC(\\text{Given Matrix}\\quad\\Rightarrow\\quad)
context.NC()
matrixOP.write(mat)
context.NR()
context.NC()
context(\\text{Upper Triangular}\\quad\\Rightarrow\\quad)
mat = matrixOP.upperTri(mat)
context.NC()
matrixOP.write(mat)
context.NR()
\stopluacode
\stopalign\stopformula
\stoptext
Sometimes, I got “-0” as an entry of matrix after calculation but I couldn’t
resolve it(I asked about it to this list before).
Thank you.
Best regards,
Dalyoung

Re: [NTG-context] Simple command with variable number of arguments
Thanks Otared,
that looks very promising. My attempt to wrap the arguments with \NC \NR fails,
though.
It looks like only the first argument is used, and I am clearly missing
something.
Also, I’d like to use the example you posted but without the last comma so that
in the example below
I get (4,5) instead of (4,5,).

Surprisingly, this is not as simple as it may seem at first glance. Some
time ago, I had written a module to achieve this. See attached. The usage
is:
\usemodule[simplematrix]
\definesimplematrix[MATRIX][fence=bracket]
(any predefined math-fence will work) and then:
\MATRIX{1,2,3} for row vectors and \MATRIX{1;2;3} for column vectors, and
\MATRIX{1,2,3; 4,5,6} for matrices.
You can use \definesimplematrix[...][distance=..., align=...] to influence
the distance and align keys of mathmatrix.

Re: [NTG-context] Simple command with variable number of arguments
Dear Luigi and listers,
Last year, I need to write a text for a linear algebra class.
Since there are many \startmatrix … \stopmatrix and matrix calculations, I
wrote a lua code which did matrix calculations and writing with a lot of help
from this list.
Using the code, I can write class materials easily. It is good enough for my
purpose.
I am not good in Lua coding, so there may be many things to be checked for
efficiency and for stability.
However, I attached the code because there may be someone who need it.
It is also good thing to return what I get from the list back.
I hope that you enhance the code for better performance since you are an expert
in Lua.
I always thank to this list and to developers of ConTeXt.
Best regards,
Dalyoung

Re: [NTG-context] Simple command with variable number of arguments
Dear Hans, Thank you for checking and enhancing. I also got an error at “uppertri” as you point out. The version that I have sent is one in my notebook which may be different from that in the desktop at school. When I made a class material, it worked fine. I have to check it and send it to you again. I appreciate you for making it more usable for ConTeXt users. I also found that there is a matrix module for lua programming. It is nice for the calculation of matrix, but I have a difficulty to typeset the result. That’s why I try to write a code even though I am not good in Lua programming. If it is easy to take over the result into TeX, using the lua module is much efficient and correct, I think. Anyway, I hope that it helps to typeset matrices. Best regards, Dalyoung Hi, Can you check the attached? The uppertri is wrong but it was already wrong (e.g. sign is used but never assigned). I inlined some code so ... I think there were some more errors (obscured by the fact that that piece of code is not reached). We can turn this into m-matrix or so, maybe we need to add some more.
