Access data using genvarname

Hello,

I got the following question and hope that you can point me to the right direction. Consider the following:

a = 5;

b = struct;
b.data_5 = dataset;

c = genvarname(['b.data_' num2str(a)]);

c should now contain the dataset stored in b.data_5, can you help me how to achieve that? The problem is that a is dynamic, otherwise there wouldn't be such a problem.

Thank you very much.

How about just using dynamic fieldnames?

a.someString = pi
fn = fieldnames(a);
a.(fn{1})

What are you trying to do?

For your example:

b.a5 = pi
b.(['a' num2str(5)])

OMG, of course. Sorry just didn't see it after some hours of coding and went crazy about that not working. :-) THX
