Hi All
I am trying to use function eval to a structure variable. For sake of simplicity, first create a structure sv as

sv.f1=5;
sv.f2=6;

The question is I can't access the fields of sv using

eval('sv').f1

Any suggestion? Thanks in advance.

Why do you think you need to use eval?
You should try to avoid using eval if at all possible.

See the answer to Q4.6 of the MATLAB FAQ at:

It may be of some use to you.

sv.('f1') is equivalent to sv.f1 so you can do something like:

for n = 1:10
sv.( ['f' num2str(n)] )
end
