vdotm ( v m -- p )
Matrix operations

Prev:	m~ ( m1 m2 epsilon -- ? )
Next:	mdotv ( m v -- p )

Vocabulary
math.matrices

Inputs

v	a sequence
m	a matrix

Outputs

p

a matrix

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

Notes

•	This word is the swapped variant of mdotv.
•	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 ; { 2 1 0 } { { 1 -1 2 } { 0 -3 1 } } vdotm .
{ 2 -5 5 }
