Any Error? Please note your file name is res_5500, not res5500.

i cannot get the proper answer with this code, what wrong with this code? file name is res_5500

[Guillaume]

what wrong with this code?

Lots. For a start, it's not commented so we have no idea what it's trying to do. Then, we have some variables that are created but never used (eg, a). There's also some useless statements (the clear allnames) and of course, converting a table to a cell array is probably a complete waste of time. tables are usually easier to work with than cell arrays.

We also don't know how the table is created from your csv file (just a plain readtable, or something more advanced?)

And again, we don't know what the code is meant to do.

f = fopen('path_to_file\res_5500.csv'); 
c = textscan(f,'%s','delimiter','\n'); 
fclose(f);

n = cellfun(@numel,regexp(c{:}(2:end),'\<\d'));
a = unique(n);
out = [a, histcounts(n,[a;a(end)+1])'];
