changing the Z component of a current loop

Hi everyone.

I found this file in this side: http://www.mathworks.com/matlabcentral/fileexchange/42329-magnetic-field-of-a-circular-current-loop-using-biot-savarts-law/content/Biot_3d.m

and I have been really happy with it so far. But now I want to change the angle of the current loop. So I want for example to have the loop make a 65 degrees angle with the 'ground' and not the 90 degrees angle is makes now. Like now the loop stands like this: | when looked at it form the Z-Y plane. but I want it to look like this: /

Does anyone know how to do this?

Thanks in advance
