I have a char array of strings (each string is a file name) and I would like to find out the strings that ends with xls or xlsx. I know that strcmp can be used only if to compare the first few characters, which is the opposite of what I intent to do---compare the last few characters.
What should I do in this case? Thank you.

str='abc.xlsx xls.m df.xls er.doc sd.xls'
out=regexp(str,'\S+\.xlsx?\>','match')

I would use this simpler regex:
regexp(str, '\.xlsx?$', 'match', 'once')
Matches '.xls', followed by an optional 'x', followed by the end of the string.

The findstr function may do what you want:
fn = 'filename.xlsx';
xls_pos = findstr(fn,'xls')
xls_pos =
10
So if ‘xls_pos’ (in this example) is not empty, the string contains ‘xls’ or ‘xlsx’.
