NCMatrixToPermutation[aMatrix]

Aliases: None.

Description: NCMatrixToPermutation[aMatrix] returns the permutation associated with the permutation matrix, aMatrix. Basically, it is the inverse of NCPermutationMatrix.

Arguments: aMatrix must be matrix whose columns (or rows) can be permuted to yield the identity matrix. In other words, aMatrix must be a permutation matrix. For example, if m = $\{\{0,0,0,1\},\{1,0,0,0\},\{0,0,1,0\},\{0,1,0,0\}\}$, then NCPermutationMatrix[m] gives $\{2,4,3,1\}$.

Comments / Limitations: None.
