struct res

double predict_label1[3][1];

[Repeater]

res = svmpredict(LabelS1,SStest1, model);

res is a kind of object. This is like saying:
int = 7;


If you want to use an object of type res , create one:
res someNewObject;


As an aside, you are definitely making this very hard for yourself by using enormous numbers of two dimensional arrays.
