Planar Array Antenna implementation on MATLAB

Hello, I need woodward-lawson method for Planar Array Antenna implementation on MATLAB Please see the attached image, Attached equations are for Linear array antenna but i need for planar array implementation in Matlab. The results should be in graphical format similar to the attachment 2. Attached result range is -35 to 145 my requirement is -20 to 20 This should be a simple job for Matlab Expert and should not take much time. More detail can be provided. I need this to be done within one week. If you need more details I can provide you with that. (Reference: chapter n0 7 Antenna Theory by Balance)
