I have problems using function isempty(x) when x is in the class of dataset. For example,
>> x=randn(100,10); >> xx=dataset(x); >> isempty(xx) ??? Reference to non-existent field 'nobs'.
Error in ==> dataset.isempty at 11 t = (a.nobs == 0) (a.nvars == 0);
I think this is because when I use 'dataset', only certain fields are created, which does not include the field 'nobs'. When isempty.m tries to locate this field, the error occurs. However, I am not sure how to solve this problem. Can anyone help me with this please?
Thanks in advance.

I have figured out this problem. I have additional toolbox installed which overlaps the function dataset. Once I have it removed, everything is working fine.
