Sorting a cell of strings using a certain character position
I have a variable called var= vart=[{'Ice011_L_3of3m.mat''}; {'Ice011_P_1of3m.mat'} ;{'Ice011_P_2of3m.mat'}] We would need to sort the strings in the cell array using the 10th character of each string, so we would get the following result var_sorted =[{'Ice011_P_1of3m.mat'}; {'Ice011_P_2of3m.mat'} ;{'Ice011_L_3of3m.mat'}]

vart = {'Ice011_L_3of3m.mat';'Ice011_P_1of3m.mat';'Ice011_P_2of3m.mat'}
[~,idx] = sort(cellfun(@(v)v(10),vart));
vart = vart(idx)
If you need to match more than one digit you could use a regular expression, e.g.:
[~,idx,] = sort(str2double(regexp(vart,'(?<=_)\d+','match','once')));
