can anyone help me with writting a matlab m file that can perform these following task.
1-Compute the radiated power pattern for far field (meaning do the integral) for small hertzian dipole
2-plot the power pattern in 3D
I realize that the close form solution is hard to derive without advanced math class, please help
cheers
 
First, "small" is relative. Giant, huge hertzian dipoles have exactly the same pattern as itsy-bitsy, teeny-weeny hertzian dipoles (each at their own resonant frequency).

Here's a link with some related math-stuff:

By the way, when you're done, make sure the sphere integrates to exactly 0.0 dBi.
 
I think some of what you asked for can be found in Antenna Design by Balanis, if not then that book displays a nice easy mathematically approach which you should be able to write in matlab. Using MathCAD is also very easy for postprocessing if you want to take it further
