ids1='519448(EPS1MN)' '519448(EPS2MN)' '519448(EPS3MN)' '519448(EPS4MN)' '519448(EPS5MN)' '519448(LTMD)' '519448(P)' '519448(DPS)' '519448(EPS)'

I want to find the cell that has embedded in it EPS1MN ,....EPS5MN

writing the following codes:

x2a=find(~isempty(strfind(ids1,'EPS1MN'))); % select rows.
    x2b=find(~isempty(strfind(ids1,'EPS2MN'))); 
    x2c=find(~isempty(strfind(ids1,'EPS3MN'))); 
    x2d=find(~isempty(strfind(ids1,'EPS4MN'))); 
    x2e=find(~isempty(strfind(ids1,'EPS5MN')));

is returning a value of 1 for x2a...x2e which is obviously wrong since the answers should be 1,2,...5

I am wondering what went wrong?

the two answers work well with EPS1...EPS5 but they fail to identify the cell when the cell is (P). (i.e I want the answer to identify cell '519448(P)' and gets an answer of 7. Any help with this?

If we give you the solution with (P), you will ask again it's not working with (T) or another string!
