MATLAB This is a MATLAB question. It please do not answer with a mathematical answer as it is the MATLAB code that I am looking for. Thank you.

Radiation intensities (Watts/unit solid angle) of two different lossless antennas are given as

Do (a) and (b) by using MATLAB: a) Plot the radiation intensities at polar coordinates on x-y and y-z planes for both of the antennas. Normalize the plots as maximum value to be 1.

b) Sample the radiation intensities with pi/2 radian steps in both theta and phi, and determine the directivities of both antennas numerically

You can ignore most of the engineering jargon and just write the code in MATLAB for the functions as described.
