<random-unit-matrix> ( m n max -- matrix )
Extra matrix operations

Prev:	<random-integer-matrix> ( m n max -- matrix )
Next:	invertible-matrix? ( matrix -- ? )

Vocabulary
math.matrices.extras

Inputs

m	an integer
n	an integer
max	a number

Outputs

matrix

a matrix

Word description
Creates a m x n matrix full of random, possibly signed floats as a fraction of max.

Notes

•	The signedness of the numbers in the resulting matrix will be randomized. Use mabs with this word to generate a matrix of random positive numbers.
•	This word is the real variant of <random-integer-matrix>.
•	This word is implemented by generating sub-integral floats through random-units and multiplying by random integers less than or equal to max.

Examples
