Sorting a cell array in matlab

Question

I have an array of 81x1 cell of str. which looks like this, '1.png' '2.png' '100.png' '43.png' '20.png' '32.png' '98.png' and so on. I am trying to sort it using the sort function. sort(A) but it doesnt sort it. what should I do?

Answer 1

Remove .png using regexprep or strrep, convert the remaining string to double and then use sort to get the sorted indices. Use these sorted indices to sort the cell A.

[~, ind] = sort(str2double(regexprep(A,'.png','')));
A = A(ind);
