Dear Proch?zka Luk?? Ing and Hans,
Thank you for the reply.
It works fine.
I modify your code to write a matrix and it also works too.
\startformula
\startluacode
local NC, NR = context.NC, context.NR
local t = {{1,0,3,4},{0,2,-2,5},{0,0,1,2}}
context.startmatrix() --"{left={\left (\,},right={\,\right)}}")
for _, r in ipairs(t) do
for _, c in ipairs(r) do
NC()
context(c)
end
NR()
end
context.stopmatrix()
\stopluacode
\stopformula
But I couldn't put "( )" before and after matrix.
If I use
context.startmatrix("{left={\left (\,},right={\,\right)}}")
then it wrote "left…" as text before the matrix.
How to enclose matrix with ( )?
Thank you again.
Best regards,
Dalyoung
