Hey,

I have two cell arrays of string. Let's call them A and B:

A = {'test1', 'test2'};
B = {'here_test2_occurs', 'here_test1_occurs'};

I know that the elements of A occur in the elements of B. How can I reorder the cell array A so that the elements are in the same order as they occure in B?

Thanks!

Assuming that every text in B contains exactly one text from A, and that every text in A occurs in B:

A = {'test1', 'test2', 'test1'};
B = {'here_test2_occurs', 'here_test1_occurs'};
F = @(a)find(contains(B,a));
[~,X] = sort(cellfun(F,A));
C = A(X)
C = 1×3 cell array
    {'test2'}    {'test1'}    {'test1'}
