Hi All,
I want to use a new vector every time in my function using for loop. My code is as follows:
for g=1:40
hac=ret(str2num('g'));
results=nwest(hac,ones(length(hac),1),4);
out{1,g}=results;
end;
I want vector/matrix ret to change as ret1,re2.....ret40. The above code produces error. problem is in line2.
Help will be appreciated.
Regards,
AMD.

try
eval(sprintf('ret%d',g))
But please read the following link

@Ahmad: Believe the FAQ and consider, that including an index in the name of the variable is a bad programming practice, while using an index as index is fast, clean and flexible.
