Transform Cartesian coordinates to spherical
Syntax
Description
[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.
Algorithm
