MAKEMAT(expression, n, [m])


Make Matrix. Creates a matrix of dimension n × m, using expression to calculate each element. If expression contains the variables I and J, then the calculation for each element substitutes the current row number for I and the current column number for J. With two arguments, this creates a vector of size n.


MAKEMAT(0,3,3) returns [[0,0,0],[0,0,0],[0,0,0]] MAKEMAT(√2,2,3) returns [[√2,√2,√2],[√2,√2,√2]] MAKEMAT(I+J–1,2,3) returns [[1,2,3],[2,3,4]] MAKEMAT(√2,2) returns [√2,√2]
