I am attempting to count the number of times each row occurred in a table. i have the table( 5 row, 2 column)
a=
'b2' 'YE'
'b2' 'YE'
'b5' 'HN'
'b5' 'HN'
'b6' 'NV'
I want to get the output
b=
'b2' 'YE' 2
'b5' 'HN' 2
'b6' 'NV' 1
Is there anyway to solve this?

a = {'b2' 'YE'
'b2' 'YE'
'b5' 'HN'
'b5' 'HN'
'b6' 'NV'};
[a1,~,c] = unique(a,'stable');
cc = reshape(c,size(a));
[n,~,c1] = unique(cc,'rows','stable');
out = [a1(n),num2cell(histcounts(c1,1:max(c1)+1)')]

Check out unique() with the 'rows' option.
