how to assign angle

Hi to all I am fine and hoping for the same. I want to take cos(theta) of the angle but for a = 1 and b = 1 angle should be 0 and for a = 1 and b = -1 it should be 180. The result should be in matrix form again. File attached.

Regards

You do not multiply a and b by the cosine. You multiply a and b by pi and put it inside the cosine, cos(), OR multiply by 180 and put inside cosd(). See if that hint can help you. meshgrid() may also help.

I have just assumed a and b as in the prg my concern is for a = 1 and b =1 the angle should be 0 and for a = 1 and b=-1 angle should be 180 or it can be pi

So? Just use b*pi and you're all set.
