Skip commas inside brackets when the expression has operators

Hi all,

I am trying to split a string

"A(B,'C'),D(E,'F'),'==','G','H"

using strsplit so that I get these separately

A(B, 'C')

D(E, 'F')

'=='

'G'

'H'

Any help would be appreciated.

Maybe look into regex or Matlab's new "patterns".

Hi Dhanesh Kumar,

I understood that you are trying to split the string at commas except that within the brackets.

The function “regexp” can be used to match the expression and eliminate the commas:

For example,

test = 'Ram,C,D,GH(cat,abc,6),,xyz';

regexp(test,'\w+(\([^)]+\))?', 'match')

Reference link: Function "regexp"

Hope this helps you!!

[Xingwang Yong]

expr1 = '(?<=\([^)]*),(?=.*\))'; % comma inside parenthesis, like '(..., ...)' 
index_comma_in_paren = regexp(line, expr1);

Once I did this for my file exchange submission alignMatrix.m. Hope it helps.
