The inputs x, y (, and z) must be the same shape, or scalar. If called with a single matrix argument then each row of C represents the Cartesian coordinate (x, y (, z)).
theta describes the angle relative to the positive x-axis.
r is the distance to the z-axis (0, 0, z).
If only a single return argument is requested then return a matrix P where each row represents one polar/(cylindrical) coordinate (theta, phi (, z)).
[x, y] = pol2cart (theta, r) ¶[x, y, z] = pol2cart (theta, r, z) ¶[x, y] = pol2cart (P) ¶[x, y, z] = pol2cart (P) ¶C = pol2cart (…) ¶Transform polar or cylindrical coordinates to Cartesian coordinates.
The inputs theta, r, (and z) must be the same shape, or scalar. If called with a single matrix argument then each row of P represents the polar/(cylindrical) coordinate (theta, r (, z)).
theta describes the angle relative to the positive x-axis.
r is the distance to the z-axis (0, 0, z).
If only a single return argument is requested then return a matrix C where each row represents one Cartesian coordinate (x, y (, z)).
[theta, phi, r] = cart2sph (x, y, z) ¶[theta, phi, r] = cart2sph (C) ¶S = cart2sph (…) ¶Transform Cartesian coordinates to spherical coordinates.
The inputs x, y, and z must be the same shape, or scalar. If called with a single matrix argument then each row of C represents the Cartesian coordinate (x, y, z).
theta describes the angle relative to the positive x-axis.
phi is the angle relative to the xy-plane.
r is the distance to the origin (0, 0, 0).
If only a single return argument is requested then return a matrix S where each row represents one spherical coordinate (theta, phi, r).
[x, y, z] = sph2cart (theta, phi, r) ¶[x, y, z] = sph2cart (S) ¶C = sph2cart (…) ¶Transform spherical coordinates to Cartesian coordinates.
The inputs theta, phi, and r must be the same shape, or scalar. If called with a single matrix argument then each row of S represents the spherical coordinate (theta, phi, r).
theta describes the angle relative to the positive x-axis.
phi is the angle relative to the xy-plane.
r is the distance to the origin (0, 0, 0).
