Thread Subject: regexprep wildcard problem

Hello,

Regexp and regexprep are great functions but for someone
who has not a very large history in programming the way
wildcards are dealt with in the code is a bit hard to
understand and the help file is not as complete as I had
hoped. However I need something replaced in my code and
maybe someone could help me.

I have the string 'atp[c]' which needs to be transformed
into 'atp', the same counts for 'atp[p]'.

I tried
regexprep({'atp[c]','atp[p]'}, '[]', '')
and
regexprep({'atp[c]','atp[p]'}, '[(\w+).*?]', '')
and many more but mostly the results are '[]' or atp[ or
atp[] but never 'atp'. I am at a loss, and I know it is
possible.

thanks

one of the many solutions

     s={'abc[c]','defg[C]hi','j[dDd]'};
     m=regexp(s,'\w*(?=(\[))','match');
     r=[m{:}];
     disp(r)
% ans = 'abc' 'defg' 'j'

What are those SNIP comments?

About the extra post, was an accident, I tried to remove
it but that does not seem possible.

I tried your piece of code with regexprep but I got for
example from {'atp[c]', 'atp[p]'}
[c]
[p]

and i needed:
atp
atp

i tried to move the /w* because i think that was the
problem but it wasn't ofcourse.

thanks again

that's exactly what you get with the solution i've shown

     s={'atp[c]','atp[p]'};
     m=regexp(s,'\w*(?=(\[))','match');
     r=[m{:}]
% ans = 'atp' 'atp'

That is exactly right. Probably was a bit too focussed on
the regexprep. Anyway got it working now with the code
above. Many thanks.
