??? Attempt to reference field of non-structure array. Error in ==> at 11 x=data.x;

I am using a dataset heart.dat. When I run i get this error..Any suggestion/error?

Code:

data=load('heart.dat'); x=data.x; x=x';

Thanks

Does data have a field called x? If not then it clearly won't work. Do you expect it to have a field x? I don't have 'heart.dat' so I don't know what it contains.

You can look at what fields 'data' has on the command line or in the variable editor.

yes it does not contain x..actually i am doing clustering on this dataset

What are you expecting x to be then?

You get a 270*14 numeric matrix when you load that data, not a struct. If you want a specific column of the data you can use e.g.

x = data(:,1);

but it depends entirely what you want to access from the data.
