Unique elements in cell array
function [Au, idx, idx2] = uniquecell(A)
Same as built-in unique, but works for cell arrays where each element is a numeric array.
For A a cell array of matrices (or vectors), returns Au, which contains the unique matrices in A, idx, which contains the indices of the last appearance of each such unique matrix, and idx2, which contains th indices such that Au(idx2) == A
Example usage:
A = {[1,2,3],[0],[2,3,4],[2,3,1],[1,2,3],[0]};
[Au,idx,idx2] = uniquecell(A);
Results in:
idx = [6,5,4,3]
Au = {[0],[1,2,3],[2,3,1],[2,3,4]}
idx2 = [2,1,4,3,2,1]
Algorithm: uses cellfun to translate numeric matrices into strings then calls unique on cell array of strings and reconstructs the initial matrices.
