- function [x,y,z] = sph2cart(az,elev,r)
- %SPH2CART Transform spherical coordinates to Cartesian.
- % [X,Y,Z] = SPH2CART(AZ,EL,R) transforms data stored in spherical
- % coordinates to Cartesian coordinates. If [M,N] = SIZE(AZ), then
- % EL and R must be also be the same size. AZ and EL must be in radians.

- z = r .* sin(elev);
- x = r .* cos(elev) .* cos(az);
