shufflelabel randomly changes the order of label values in a label matrix. Zeros and nans are ignored. The label matrix can be every numerical data type, char or a cell array of strings.

Example

L = kron([1 2 3;3 2 3],[1 1; 2 2])

L =

1 1 2 2 3 3
2 2 4 4 6 6
3 3 2 2 3 3
6 6 4 4 6 6

Ls = shufflelabel(L)

Ls =

3 3 6 6 1 1
6 6 2 2 4 4
1 1 6 6 1 1
4 4 2 2 4 4
