n*m ( n m -- m )
Matrix operations

Prev:	n-m ( n m -- m )
Next:	n/m ( n m -- m )

Vocabulary
math.matrices

Inputs

n	an object
m	a matrix

Outputs

m

a matrix

Word description
Every element in the input matrix m is multiplied by the scalar n.

Notes

•	The shape of the input matrix is preserved in the output.
•	This word is the swapped variant of m*n.
•	This word is intended for use with "flat" (2-dimensional) matrices.
•	This word assumes that elements of the input matrix are compatible with the following words: * ( x y -- z )

Examples
