Actually the method matrix.power(n)
works properly. What you are looking for is a function which applies an exponent to each element.
What matrix.power(n)
is doing:
http://mathonline.wikidot.com/powers-of-a-matrix#toc0
I have to see through all the functions and conceps where such element-wise power function would fit into or if it already exists. This is called Hadamard product.
Reference:
https://en.wikipedia.org/wiki/Hadamard_product_(matrices)
from la4j.
There is now a new method Matrix.hadamardPower(int n)
which technically does what was asked for. Please try out.
This function uses the Hadmard product in order to produce Matrices with powers of n for each element. This function does not modify the origin matrix, a new matrix is created. When n=1
a copy of the source matrix is returned. As ⊚ is used to symbolize the Hadamard product operator, the operation looks like:
(A⊚B)ij = (A)ij⊚(B)ij
There are also test cases included for demonstration.

Thank you, Oliver.
