Dear friends,

I have a list of file names stored in a cell and I would like to sort this names. My cell variable is b:

Workspace: b < 15x1 cell>

b =

    'p1-cimg.txt'
    'p11-cimg.txt'
    'p12-cimg.txt'
    'p13-cimg.txt'
    'p14-cimg.txt'
    'p3-cimg.txt'
    'p4-cimg.txt'
    'p5-cimg.txt'
    'p6-cimg.txt'
    'p7-cimg.txt'
    'p8-cimg.txt'
    'p9-cimg.txt'
    'p10-cimg.txt'
    'p15-cimg.txt'
    'p2-cimg.txt'

I would like perform an ascending sort and obtain:

 b=
'p1-cimg.txt'
'p2-cimg.txt'
'p3-cimg.txt'
....

Anyone knows how to do that?

I tried use sort, but I got this error: >> sort(b) Error using sort Input argument must be a cell array of strings.

Thank you very much!

Given your b, try this:

    num = cellfun(@(x) sscanf(x,'p%f-cimg.txt'),b) ;
    [~,sortindex] = sort(num)
    b(sortindex)
