Write a user defined MATLAB function that determines the cross product of two vectors For the function name and arguments, use W = Cross(V,U). The input arguments V and U are the vectors to be multiplied. The output argument W is the result (three-element vector).(a) Use Cross to determine the cross product of the vectors v = i + 2j + 3k and u = 3i + 2j + k.(b) Use Cross to determine the cross product of the vectors v = -2i + j - 3k and u = i + j + k.
