I have vector named classes
I need to compare all classes element with
D = dataset(dataset(:,p)==X,:);
Briefly equation above should compareing with all classes elements, for my example X should be 1 or 2
X can be any element of classes vector, in my code i compare p th element of the dataset array with X , X is one of the elemeny of classes vector.
I just create a example classes matrix it can be any array.
