Word description
Because it is nonsensical to raise a number to the power of a matrix, this word exists to save typing swap m^n. See m^n for more information.
Errors
negative-power-matrix if n is a negative number other than -1.
undefined-inverse if n is -1 and the multiplicative-inverse of m is undefined.

Notes
| • | This word is the swapped variant of m^n. |
| • | 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: max ( obj1 obj2 -- obj ) abs ( x -- y ) / ( x y -- z ) |
Examples
USING: math.matrices.extras prettyprint ;

{ { 7 10 } { 15 22 } }
{ { 7 10 } { 15 22 } }
