Hello together,
I was trying to do some regurlare expression, I am getting correct output which i was expecting. can you please help me
myinp = {['getval' ('MYINFO\ECE1') '==19 & (getval(' 'MYDataCode\CSE' ') >= 4) & (getval(' 'MYCHANGE\DEPT' ') < 6'] };
[a,b]=regexp(myinp,'([^"])','tokens');
%expected output should be like
a{1,1} = getval('MYINFO\ECE1')
a{1,2} = getval('MYDataCode\CSE')
a{1,3} = getval('MYCHANGE\DEPT')

this is my input
myinp = {['getval(' '''MYINFO\ECE1''' ')' '==19 & (getval(' '''MYDataCode\CSE''' ') >= 4) & (getval(' '''MYCHANGE\DEPT''' ') < 6)'] }
myinp = 1×1 cell array
{'getval('MYINFO\ECE1')==19 & (getval('MYDataCode\CSE') >= 4) & (getval('MYCHANGE\DEPT') < 6)'}

Your text does not have any double quote characters, that regular expression will match everything.
What is the purpose of the superfluous scalar cell array?

Maybe this is what you need?
myinp = {['getval(' '''MYINFO\ECE1''' ')' '==19 & (getval(' '''MYDataCode\CSE''' ') >= 4) & (getval(' '''MYCHANGE\DEPT''' ') < 6)'] };
[a,b]=regexp(myinp{1},'getval\(''([^'']*)''\)','match')
a = 1×3 cell array
{'getval('MYINFO\ECE1')'} {'getval('MYDataCode\CSE')'} {'getval('MYCHANGE\DEPT')'}
b = 1×3
