MATLAB: Remove parenthesis and the contents inside from a string

Question

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));

Answer 1

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