m~ ( m1 m2 epsilon -- ? )
Matrix operations

Prev:	m/ ( m1 m2 -- m )
Next:	vdotm ( v m -- p )

Vocabulary
math.matrices

Inputs

m1	a matrix
m2	a matrix
epsilon	a number

Outputs

?

a boolean

Word description
Compares the matrices like ~, using the epsilon.

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 epsilon -- ? )

Examples
In the example, only .01 was added to each element, so the new matrix is within the epsilon .1of the original.
