Remove parenthesis and the contents inside from a string

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));

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

B = 'abc'

Hi @Stephen Cobeldick

If we have something like this:

S = {'A(+229.16)AAAAAAAAW'

'AAA(+148.52)DETLRLW'

'AA(+155.89)ALPAAALW'};

How can we remove (+*) from middle?

I need to have the following array:

S = {'AAAAAAAAAW'

'AAADETLRLW'

'AAALPAAALW'};

Thanks in advance,

Moh

Perhaps one of these:

S = {'A(+229.16)AAAAAAAAW'
    'AAA(+148.52)DETLRLW'
    'AA(+155.89)ALPAAALW'};
A = regexprep(S,'[^A-Z]+','')

A = 3×1 cell array
    {'AAAAAAAAAW'}
    {'AAADETLRLW'}
    {'AAALPAAALW'}

B = regexprep(S,'\([^)]+\)','')

B = 3×1 cell array
    {'AAAAAAAAAW'}
    {'AAADETLRLW'}
    {'AAALPAAALW'}

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?

"I mean to extract the only the characters that exist in brackets without the others."

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

B = 'ABC'

A = 'abc (ABC)' ; 

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