frequency of occurrence of the rows in a table

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)')]

Thank you so much Andrei Bobrov. That solved my problem.

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