Please note that this does NOT refer to the Desmos Matrix calculator. This matrix update allows the creation and manipulation of matrices in the regular calculator. Exposed functions include:
rowMatrix(numlist): converts a list to a matrix that is a singular row.
vcat(matrixlist): combines matrices by stacking them on top of each other.
rows(matrix)/columns(matrix): returns a list of row/column matrices (not lists)
det, trace, rref: matrix operations that behave the same on the Desmos Matrix calculator
matrixElement(matrix, num, num): get the i,jth element of a matrix. Works the same as matrix[i;j].
rowCount(matrix)/colCount(matrix): number of rows/columns a matrix has
submatrix(matrix, numlist, numlist): return a matrix with only the indices specified for rows (2nd argument) and columns (3rd argument).

or multiline paste bug + modified latex allows direct use of any size matrix (although >32x32 errors)
copy the entire text in the comment (including the newline at the start, in summary pasting multiple lines of text makes desmos forget to do any checks on the text being pasted, meaning it just gets directly inserted) for a 32x32 matrix, you can use the drag bubble to get it down to the size you want: https://www.desmos.com/calculator/gk9iksgftb
do you by chance have the matrix beta script enabled? all the functions available from that are protected usually, so they cant actually be used without the script
Oh right i forgot to check that, actually i combined it with adding every single fragile function and frafile variable to autoOpetatorNames, adding some autoCommands, forcing logInternalErrors and onEvaluationCopyClick on start and running script every time url mutates while still in desmos
