Function Details

cartesian_to_spherical(vector)

Convert the Cartesian vector [x, y, z] to spherical coordinates [r, theta, phi].

The parameter r is the radial distance, theta is the polar angle, and phi is the azimuth.

Parameters:

• vector (numpy rank-1, 3D array) - The Cartesian vector [x, y, z].

Returns: numpy rank-1, 3D array

The spherical coordinate vector [r, theta, phi].

spherical_to_cartesian(spherical_vect, cart_vect)

Convert the spherical coordinate vector [r, theta, phi] to the Cartesian vector [x, y, z].

The parameter r is the radial distance, theta is the polar angle, and phi is the azimuth.

Parameters:

• spherical_vect (3D array or list) - The spherical coordinate vector [r, theta, phi].
• cart_vect (3D array or list) - The Cartesian vector [x, y, z].
