Matrix operations

Prev:	vdotm ( v m -- p )
Next:	mdot ( m m -- m )

Vocabulary

Inputs

m	a matrix
v	a sequence

Outputs

p

a matrix

Word description
Computes the dot product of a matrix and a vector.

Notes

•	This word is the swapped variant of vdotm.
•	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 } } { 2 1 0 } mdotv .
{ 1 -3 }
