Problem #3 Write a MATLAB user-defined function named calcz.m that has two input arguments and one output argument. The input arguments are: column vectors a and b of the same length The output argument is a column vector z whose elements are calculated using the formula shown below, where m is the length of the input vectors, and i denotes the ith element of each input vector. In the code of your user-defined function, the calculation of Z muse use a for-loop
