That was stupid of me. I can do it by containing a generalized fraction within \( and \).

You can choose the names pmatrix, etc as you wish. There is even a module which allows you to compute the product of two matrices, etc (with \usemodule[m-matrix], see m-matrix.mkiv). %% defining matrix with parentheses \definemathmatrix[pmatrix] [matrix:parentheses] [simplecommand=pmatrix] %% defining matrix with brackets \definemathmatrix[bmatrix] [matrix:brackets] [simplecommand=bmatrix] %% defining determinant with bars \definemathmatrix[determinant] [matrix:bars] [simplecommand=thedeterminant] \starttext Let $A$ be the $3\times 3$ matrix defined by \startformula A := \startpmatrix \NC 11 \NC 12 \NC 13 \NR \NC 21 \NC 22 \NC 23 \NR \NC 31 \NC 32 \NC 33 \NR \stoppmatrix . \stopformula This matrix can also be dfined by the Matlab structure of a matrix: \startformula A := \pmatrix{11,12,13 ; 21, 22, 23 ; 31, 32, 33} \stopformula Compute the value of \startformula \alpha := \thedeterminant{11,12,13 ; 21, 22, 23 ; 31, 32, 33} = {\rm det}(A). \stopformula \stoptext Best regards: Otared K. > On 15 Jul 2020, at 15:38, David Eric Cox <davidericcox@protonmail.com> wrote: > > Can anyone direct me to either traditional ConTeXt math documentation on how to produce matrices or tell me how to show a variable in bold red in MathML?
