function [az,elev,r] = cart2sph(x,y,z)
%CART2SPH Transform Cartesian coordinates to spherical.
%	[AZ,EL,R] = CART2SPH(X,Y,Z) transforms data stored in Cartesian
%	coordinates to spherical coordinates. If [M,N] = SIZE(X), then
%	Y and Z must be also be the same size.  AZ and EL are in radians.

r = sqrt(x.^2+y.^2+z.^2);
elev = atan2(z,sqrt(x.^2+y.^2));
