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

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

Great! That works beautifully!
What did you use the second statement for? Just to ensure the cell array is horizontal?

Yes. If your cell array is really vertical and you want to keep it that way, just delete the 2nd line and concatenate vertically in the final line.

Thanks Matt. I had another problem while using this. I had used a cell sorting function, for which I had to convert the cell array to char. So in Workspace, the cell contents show up with three apostrophes. This causes the strfind to not work (error: If any of the input arguments are cell arrays, the first must be a cell array of strings and the second must be a character array). If I do a 'iscellstr' to my array, it returns 1, meaning it is a cell array of strings. Do you know what those three apostrophes mean? I'm not familiar with that. Also, if I delete another column in that cell array, the apostrohes disappear, and now I can use the code you pasted, no problem. I'm stumped.
