MATLAB: How to move certain rows up or down in a cell array

Question

I have a cell array, which is sorted alphabetically. I need to move any row that contains a marker (for example, X), to the top of the list. How do I do that?

e.g.:

AAA AAB FFF FTD JJJ XXX XXY ZAF ZAE

So, I just need to move XXX and XXY to the beginning, and the rest of the array should remain the same.

Does anyone know of a script to do this automatically?

Thanks

Answer 1

idx=~cellfun('isempty', strfind(yourcell,'X'));
yourcell=yourcell(:).';
yourcell=[yourcell(idx), yourcell(~idx)];
