Transform Cartesian coordinates to polar or cylindrical
[THETA,RHO,Z] = cart2pol(X,Y,Z)
transforms three-dimensional Cartesian coordinates stored in corresponding elements of arrays
Z, into cylindrical coordinates.
THETA is a counterclockwise angular displacement in radians from the positive x-axis,
RHO is the distance from the origin to a point in the x-y plane, and
Z is the height above the x-y plane. Arrays
Z must be the same size (or any can be scalar).
[THETA,RHO] = cart2pol(X,Y)
transforms two-dimensional Cartesian coordinates stored in corresponding elements of arrays
Y into polar coordinates.
The mapping from two-dimensional Cartesian coordinates to polar coordinates, and from three-dimensional Cartesian coordinates to cylindrical coordinates is
