If I have a variable x='name', how can I use x to build a structure with name 'name' that looks like:
name.a
name.b
No need to tell me about the hazards of dynamic variable naming.
Thanks.

Actually, found my own answer:
x = 'name';
eval(sprintf('%s = struct;',x));
This creates a structure named 'name' and one can use the same eval format to add fields to it later.

Thanks for the light reading. I think I am going to take this in the direction of indexing instead.
Thanks again for your help.

Would it be acceptable to use x as a dynamic fieldname instead of the top level variable name? E.g.,
v.(x).a
v.(x).b

Not really. I know about the paranthesis around field names, but it creates another level of structure. The problem is that if I am creating the structure names inside my program, I don't know how to create the structures using those names.
Thanks for your response.
