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

Prev:	m+n ( m n -- m )
Next:	m*n ( m n -- m )

Vocabulary
math.matrices

Inputs

m	a matrix
n	an object

Outputs

m

a matrix

Word description
n is treated as a scalar and subtracted from each element of the matrix m.

Notes

•	This word is the swapped variant of n-m.
•	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

USING: kernel math.matrices prettyprint ; 3 <identity-matrix> 1 m-n .
