How can I determine the frequency of a text term occurring in a matrix and add this frequency to the matrix?

I have a matrix of terms that are unique or multiple and I need to count the frequency of each unique term and add this to the matrix so that I can plot it.

An example of my dataset is below.

'CSARDLSGG##YNEQFF' 'CSARDLRPGGAYNEQFF' 'CSALGGGSTYNEQFF' 'CSALGGGSTYNEQFF' 'CSALGGGSTYNEQFF' 'CSAGVRLAGGVYQETQYF' 'CSAGTRK#NTEAFF' 'CSAGTESNTEAFF' 'CSAGTESNTEAFF' 'CSAGTESNTEAFF' 'CSAGTESNTEAFF' 'CSAGTESNTEAFF' 'CSAGTESNTEAFF' 'CSAGTESNTEAFF'

a={'CSARDLSGG##YNEQFF' 'CSARDLRPGGAYNEQFF' 'CSALGGGSTYNEQFF' 'CSALGGGSTYNEQFF' 'CSALGGGSTYNEQFF' 'CSAGVRLAGGVYQETQYF' 'CSAGTRK#NTEAFF' 'CSAGTESNTEAFF' 'CSAGTESNTEAFF' 'CSAGTESNTEAFF' 'CSAGTESNTEAFF' 'CSAGTESNTEAFF' 'CSAGTESNTEAFF' 'CSAGTESNTEAFF'};   % input

out=unique(a);     % unique values in a

for ii=1:numel(unique(a))
count(ii)=sum(strcmp(a,out(ii)));
end

unq=out'
count'

Answer 2

How do I apply a scalar?

ii =

     1     2     3     4     5     6

Error using strcmp Inputs must be the same size or either one can be a scalar.

I'm assuming you want to find frequency of numeric scalar

a=[1 2 3 4 5 6 3 4 2 3];
out=unique(a);

for ii=1:numel(out)
    count(ii)=sum(a==out(ii));
end

fulloutput=[out' count']
