Matlab, order cells of strings according to the first one

Question

I have 2 cell of strings and I would like to order them according to the first one.

A = {'a';'b';'c'}
B = {'b';'a';'c'}

idx = [2,1,3] % TO FIND

B=B(idx);

I would like to find a way to find idx...

Answer 1

This seems to be significantly faster than using ismember (although admittedly less clear than @rayryeng's answer). With thanks to @Divakar for his correction on this answer.

[~, indA] = sort(A);
[~, indB] = sort(B);
idx = indA(indB);
