Is there a neat way to remove a parenthesis and the contents inside from a string. For example the string
A = 'abc (ABC)'
% how to extract 'abc' from A, get rid of ' (ABC)' including the leading whitespace?
One cumbersome solution is:
temp = strsplit(A,'(');
B = strtrim(temp(1));

Ran in:
A = 'abc (ABC)';
B = regexp(A,'^\w+','once','match')
B = 'abc'

Excuse me I have a question.. how could you do the inverse of this??
I mean to extract the only the characters that exist in brackets without the others.
for example:
input : A = 'abc (ABC)';
output B = 'ABC'
could you please help me?

A = 'abc (ABC)';
B = regexprep(A,{'.*\(','\).*'},'')
B = 'ABC'

idx = strfind(A,' (') ;
iwant = A(1:idx-1)
