how to use strcmp within the same column

i am trying to figure out how to use strcmp within the same column

for example: in a column called col 2 which contains a,a,a,b,b,c,c,c,c,d...etc

i would like to use strcmp to do a strcmp for each cell and if they match to print out the values corresponding to that cell.

how do i do this?

Answer 1

[Azzi Abdelmalek]

s={'a';'a';'a';'b';'b';'c';'c';'c'}

Give an example, what do you want ?

maybe

b='a'
out=s(strcmp(s,b))

well i have the following code:

s= data2.REGIMEN(1);
n=0;
for i=2:length(data2)
%     
if strcmp (data2.SUBJECT,data2.SUBJECT{i})
     s=strcat(s,['||' char(data2.REGIMEN(i))]);
     n=n+1;
%  else 
%    s=data2.REGIMEN{i};

 end
 end
just can't  figure out how to use the strcmp feature

This is not clear, give an example with data

[andrew]

in column you have aaaa,bbbb,cccccc,d,eeee and lets say values for a is 1,2,3,4 if it matches ,concatenate those values corresponding to a in one cell seperated by to make it 1||2||3||4 in one cell

[Azzi Abdelmalek]

s={'a';'a';'a';'b';'b';'c';'c';'c'}
idx=num2cell(find(strcmp(s,'a'))');
q=repmat({'||'},1,numel(idx));
f=[idx ; q]
f=f(:)'
f(end)=[]
f=cellfun(@num2str,f,'un',0);
out=horzcat(f{:})

tf = ismember(TheCell, ValueToSearch);
SelectedValues = AssociatedValues(tf);
