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.

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!!

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.
