Description
This function tests whether a matrix is reducible or irreducible.
IT WILL ONLY RELIABLY WORK FOR NONNEGATIVE MATRICES (e.g. PPMs).
It works on the basis that for any matrix A, (I+A)^(s-1) where I
is the identity matrix and s is equal to the order of the matrix
is positive (Caswell 2001). The function returns the condition
"TRUE: Irreducible" or "FALSE: Reducible".
Usage
