Hi, i have 2 cells(cell1 and cell2) of size 628*1 and 244*1 respectively, and i want to compare the elements of cell 1 with the elements of cell 2 and return only the matched ones from cell1 and delete the rests

 cell1{k,1}={' *tcaa-a6-2677*';'tcca-a6-2681';' *tcca-aa-3566*';............};
 %
 cell2{k,1}={'TCCA-A6-2671-11A-01R-1758-07';' *TCCA-A6-2677*-11A-01R-0826-07';'TCCA-AA-3520-11A-01R-0721-07'; 'TCCA-AA-3528-11A-01R-1758-07'; *TCCA-AA-3566*-01A-01R-0125-07';.................}

Hints: i tried strncmpi and length, but because of size issue i get confused about which Command statement is better in my case.

After removing the asterisks, space characters, and fixing the first element of C1, this seems to do the job:

 >> C1 = {'tcca-a6-2677';'tcca-a6-2681';'tcca-aa-3566'};
 >> C2 = {'TCCA-A6-2671-11A-01R-1758-07';'TCCA-A6-2677-11A-01R-0826-07';'TCCA-AA-3520-11A-01R-0721-07';'TCCA-AA-3528-11A-01R-1758-07';'TCCA-AA-3566-01A-01R-0125-07'};
 >> fun = @(s)any(strncmpi(s,C2,numel(s)));
 >> out = C1(cellfun(fun,C1))
 out =
   'tcca-a6-2677'
   'tcca-aa-3566'

Awesome. Thanks Stephen, I had no idea about function handles using @ command.

Hello,

I have a similar need. I have 2 cells(cell1 and cell2) of size 72*1 and 110*1 respectively, and i want to compare the elements of cell 1 with the elements of cell 2 and return only the matched ones from cell1 and delete the rest.

The above mentioned solution is not working for me.

Can you please help me out with this ?

i think you match element by element but i want to check every element in cell1 with all the elements in cell 2.
