Looking for matlab code for plotting radiation pattern of broadside array antenna
For what kind of array antenna, linear, planar or circular?

In case of linear array with m-elements,
u can try this
AF=exp(-j*(2*pi/lambda)*d*sin(AOA)*[M-1]);
create a manifold table and multiply AF with it keeping AOA as 90 for broadside or 0 - 180 for endfire
Can you tell me what is meant by this manifold table? I have searched it but didn't find anything reasonable.
A manifold table is basically the response of all individual elements of an array for the signals coming from all the angles. i.e keep the array in the centre (say) and take a source (basically a signal), now rotate the source from 0 to 360 degrees (or as reqd.) and save the responses obtained. This give a lookup table or u can say a manifold table.
We cannot plot the radiation pattern but only the Array Factor, then you can apply the linear array theory, if you have a linear array!, to get the phase, and use a simulation tool such as FEKO to plot the radiation pattern
