I have a matlab struct that has a sub-element such that when I run
class(foo.bar)
Gives the error:
Error using class
The CLASS function must be called from a class constructor.
When I just run foo.bar, ans gets set several times.
How can I find out which class bar belongs to?
I suppose you have a structure array as foo. Example:
>> foo = struct('a',{1 2})
foo =
1x2 struct array with fields:
a
>> foo.a
ans =
1
ans =
2
>> class(foo.a)
Error using class
The CLASS function must be called from a class constructor.
>> class(foo(1).a)
ans =
double
Note that foo.a returns here what is called a comma-separated list.
