Write a Matlab function to do the following. Given two polynomials, defined by their coefficient vectors v and w, compute the vector u, which is the coefficient vector of the product of v and w. You can obviously not use the Matlab function "conv", but you can use it to verify your results. You cannot use more than one "for" loop. Use your function to multiply 2z z + 5 and 3z4z5+z2 +3. -
