Finds a permutation of a matrix such that its Frobenius norm with another matrix is minimized.
data matrix we want to permute
matrix whose distance with the permuted A we want to minimize. By
Finds the permutation P of A such that
||PA - B|| is minimum in Frobenius
norm. Uses the linear-sum assignment problem (LSAP) solver in the package
clue. The default B is the identity matrix of same dimension, so that the
permutation of A maximizes its trace. This procedure is useful for
constructing a confusion matrix when we don't know the true class labels of a
predicted class and want to compare to a reference class.
Permuted matrix such that it is the permutation of A closest to B
