Hello,

Thus anybody know a command for finding a string containing unknowns.
I know there is something for dir like:

txtfiles = dir([workdir '\*t?.txt'])

'*' means anything and '?' one character.
But I like to find a string like

M??T with after the M any number, between 01 and 99. So I tried

findstr(OAbinM01T.dat,'M??T')

but it didn't work.
Any one any suggestions.

Thx,

Stefan

one of the solutions

d=dir;
d={d.name}.';
r=regexp(d,'.*\.txt$','match');
r=[r{:}].';
disp(r);

The problem is finding a match in strings with unknowns. Not in dir. That thus work.
But not something like findstr(OAbinM01T.dat,'M??T')
Thanks anyone for having a look on my threath

one of the solutions

help regexp;
% then
s='OAbinM01T.dat';
