Inputs

m

a matrix

Outputs

m

a matrix

Word description
Computes the dot product of two matrices, i.e multiplies them.

Notes

•	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 ) + ( x y -- z )

Examples

USING: math.matrices prettyprint ; { { 1 -1 2 } { 0 -3 1 } } { { 3 7 } { 9 12 } } mdot .
