How is the data stored? As a char array, as a cell array each element of which is a char vector, as a string array, etc.? And which release of MATLAB are you using?

S = { 'PRS.BG02K65E5T9',
'PRS.UG02K145E5T20',
'Ark.prgrma',
'YUI_PRS.UG02K145E5T20',
'PRS.GG02K200E6T20'};
find(strncmp(S,'PRS',3))

mask = strncmp(S,'PRS',3);
row_indices = find(mask);
match_count = sum(mask);
nonmatch_count = sum(~mask);
