theta1=-180:180;
phi1=-90:90;
theta3dB=40;
[theta phi ]=meshgrid(theta1,phi1);
B=-min(12.*(theta./theta3dB).^2,Am);
how to integrate B, from theta 0 to 180?

Not sure what you meant by integrate...
But I think you might be looking for something like cumsum, have a look at this:

Since you have discrete values of theta, a cummulative sum would approximate the integration over this range.
Hope it helps!
