read the size of cell array with the same element

Hi I have a cell array looks like follows. How could I read the size of the cell array has the same element? In this case, I have 6 rows of 01.jpg so the first one is 6. I have 2 rows of 04.jpg so the second one is 2 and so forth. Thanks for your help!

01,jpg
01,jpg

Please use valid matlab syntax in your question, so it's not ambiguous. Assuming that your cell array is of the form:

c = {'01,jpg'  
     '01,jpg'
     '01,jpg'
     '01,jpg'
     '01,jpg'
     '01,jpg'
     '04,jpg'
     '04,jpg'
     '05,jpg'
     '05,jpg'}

This would work:

 [~, ~, id] = unique(c, 'stable');
 sequencelengths = diff(find(diff([-Inf; id; Inf])))

Here's one way:

C = {
'01,jpg';
'01,jpg';
'01,jpg';
'01,jpg';
'01,jpg';
'01,jpg';
'04,jpg';
'04,jpg';
'05,jpg';
'05,jpg';
}

[~,~,k] = unique(C);

C_counts = histcounts(k,[unique(k); Inf])

[u,iu]=unique(c{:},'rows');
n=histc(iu,1:length(u));
