Transform Cartesian coordinates to spherical
[THETA,PHI,R] = cart2sph(X,Y,Z)
[THETA,PHI,R] = cart2sph(X,Y,Z)
transforms Cartesian coordinates stored in corresponding elements of arrays X, Y, and Z into spherical coordinates. Azimuth THETA and elevation PHI are angular displacements in radians measured from the positive x-axis, and the x-y plane, respectively; and R is the distance from the origin to a point.
Arrays X, Y, and Z must be the same size.
The mapping from three-dimensional Cartesian coordinates to spherical coordinates is:
cart2pol Transform Cartesian coordinates to polar or cylindrical
pol2cart Transform polar or cylindrical coordinates to Cartesian
sph2cart Transform spherical coordinates to Cartesian
