[-- Attachment #1.1: Type: text/plain, Size: 354 bytes --]
Dear All,
I would like to define a command that expands
\vector{2,4} % or vector[2,4] if that’s easier
to
\startpmatrix
\NC 2 \NR
\NC 4 \NR
\stoppmatrix
and more generally
\vector{2,4,1,7}
to
\startpmatrix
\NC 2 \NR
\NC 4 \NR
\NC 1 \NR
\NC 7 \NR
\stoppmatrix
Any hints how to achieve this?
Thanks,
Matthias

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.

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.

A bit more readable: matrixOP.symMatrix = function(sym, x, y, nx ,ny) -- symMatrix("a", "m", "n") local nx = nx or 2 local ny = ny or nx local function filled(i,y) local mrow = { } for j=1,nx do table.insert(mrow, string.formatters["%s_{%s%s}"](sym,i,j)) end table.insert(mrow,"\\cdots") table.insert(mrow,string.formatters["%s_{%s%s}"](sym,i,y)) return mrow end local function dummy() local mrow = { } for j=1,nx do table.insert(mrow,"\\vdots") end table.insert(mrow,"\\ddots") table.insert(mrow,"\\vdots") return mrow end -- local mm = { } for i=1,ny do table.insert(mm,filled(i,y)) end table.insert(mm,dummy()) table.insert(mm,filled(x,y)) return mm end Also, variable nx, ny: \ctxlua{matrixOP.write(matrixOP.symMatrix("a","m","n",4,8))} Maybe this too: local default = { left = [[\left(\,]], right = [[\,\right)]], } matrixOP.write = function (t) context.startmatrix(default) for _, r in ipairs(t) do for _, c in ipairs(r) do context.NC(c) end context.NR() end context.stopmatrix() end matrixOP.writeDet = function(t) context.startmatrix(default) for _, r in ipairs(t) do for _, c in ipairs(r) do context.NC(c) end context.NR() end context.stopmatrix() end And: matrixOP.rowMult = function(t, i, m) -- replace i-th row with m*(i-th row) for k = 1, #t[i] do t[i][k] = m*t[i][k] end end matrixOP.rowMultSum = function(t, i, j, m) -- replace i-th row with i-th row + m*(j-th row) for k = 1, #t[1] do t[i][k] = t[i][k] + m*t[j][k] end end (no need for further speedup as it't non-critical code with neglectable runtime) More Luaish (local usage): matrixOP.transpose = function(m) -- transpose of a matrix local mT={} for j = 1, #m[1] do local mTrow={} for i=1, #m do local temp = m[i][j] table.insert(mTrow, temp) end table.insert(mT, mTrow) end return mT end Don't forget the local here: matrixOP.inner = function (u, v) -- inner product of two vectors local temp=0 if #u == #v then for i=1, #u do temp = temp + u[i]*v[i] end end return temp end and here: matrixOP.product = function(m1, m2) -- product of two matrices local m3={} if #m1[1] == #m2 then for i = 1, #m1 do local mrow={} for j=1, #m2[1] do local temp = 0 for k=1, #m1[1] do u = m1[i][k]*m2[k][j] temp = temp + u end table.insert(mrow, temp) end table.insert(m3, mrow) end end return m3 end less code: matrixOP.searchRow = function(m, i) local pr = #m + 1 for k=i+1, #m do if m[k][i] == 0 then k = k+1 else pr = k break end end if pr <= #m then return pr else return 0 end end Are you sure this is ok? I've added a copy as you might want to keep the original table: matrixOP.upperTri = function(m) local temp = table.copy(m) for i=1, #temp-1 do local pivot = temp[i][i] if pivot == 0 then local pRow = matrixOP.searchRow(temp, i) if pRow==0 then break end matrixOP.rowChange(temp, i, pRow) sgn=(-1)*sgn end for k=i+1, #temp do matrixOP.rowMultSum(temp, k, i,-temp[k][i]/temp[i][i]) end end return temp end So then, watch how we use the return value of this one: matrixOP.determinant = function(m) if #m ==#m[1]then local det = 1 local t = matrixOP.upperTri(m) for i=1,#t do det = det * t[i][i] end return det else return 0 end end > I always thank to this list and to developers of ConTeXt.

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).
