categorical.ipermute
categorical: A = ipermute (B, dims)
Inverse of the generalized transpose for a categorical N-D array.
A = ipermute (B, dims) returns the inverse of
the generalized transpose performed by the permute function. The
expression ipermute (permute (A, dims), dims)
returns the original array A.
dims must index all the dimensions 1:ndims (B) of the
input array B, in any order, but only once. The dimension of
B specified in dims(N) gets remapped to the
Nth dimension of A.
