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
