NCCheckPermutation[SizeOfMatrix, aListOfPermutations]

Aliases: None.

Description: If aListOfPermutations is consistent with the matrix size, SizeOfMatrix, then the output is valid permutation list. If not, the output is not valid permutation list.

Arguments: The size of a square matrix (an integer) and a list of permutations.

Comments / Limitations: If the SizeOfMatrix is n, then aListOfPermutations must be a list of $n-1$ permutations of the integers $1$ through $n$. Since this command is generally called within the context of NCLDUDecomposition the list of permutations must correspond to a list that can be used within the command.
