Failing to find a string on a cell of strings using strcmp

Hello all,

I am currently trying to use strcmp to find a string on a cell string. However, it doesn't seem to work, and I can't find why. I guess it's a matter of data types incompatibility, but I can't figure it out.

Does anybody know?

subj = {'af_p040624_hr1' 'af_p040624_hr12' 'af_p040624_hr18' 'af_p040624_hr2' 'af_p040624_hr24' 'af_p040624_hr30' 'af_p040624_hr36' 'af_p040624_hr4'};

for i=1:length(subj)
   parts = strsplit(subj{i},'_');
   if isequal(subj{i}(1:3),'af_')
      record_groups{i} = 'POAF';
      record_groups_hrs{i} = ['POAF_',parts{3}];
   elseif isequal(subj{i}(1:4),'con_')
      record_groups{i} = 'Control';
      record_groups_hrs{i} = ['Control_',parts{3}];
   end
end

hrs = {'hr1','hr2','hr4','hr12','hr18','hr24','hr30','hr36','hr42','hr48'};
for h=1:length(hrs)
   curr_hr = hrs{h};

     %I want to find the index of the record_groups_hrs which contain EXACTLY something like '_hr1'.    
     curr_recs_idx = (strcmp(record_groups_hrs,['_',curr_hr]));

end

Many thanks!

Try using 'regexp'

curr_recs_idx = regexp(record_groups_hrs,['_',curr_hr, '\>'])
