How can I perform an element-wise multiplication of 2 vectors and return the result to a vec ? Do I need to typecast them into a Mat ?

cv::Vec3f A, B, C;
//fill up A and B

C = A*B;

A*B is matrix multiplication in opencv, per element would be:

cv::Vec3f A(1,2,3), B(4,5,6), C;
multiply(A,B,C);
cerr << C << endl;
