Please can someone help. Im trying to run this code
Hw = zeros(ntrain,ntrain);
for i = 1:ntrain
for j = 1:ntrain
Hw(i,j) = Ytrain(i)*Ytrain(j)*lin(Xtrain(i,:),Xtrain(j,:));
end
end
the size of ntrain = 20
but instead the above error message being displayed.
thanks.

If lin(Xtrain(i,:),Xtrain(j,:)) is returning a vector or array, then the right hand side of the assignment would result in a vector or array, and you would then not be able to store all of that in the single numeric location Hw(i,j) that you have specified.
My guess is that lin() is probably returning a 2 x 2 array, not a scalar.
