SimPEG.utils.cartesian2spherical#
- SimPEG.utils.cartesian2spherical(m)[source]#
Converts a set of 3D vectors from Cartesian to spherical coordinates.
- Parameters
- m(
n, 3) array_like An array whose columns represent the x, y and z components of a set of vectors.
- m(
- Returns
- (
n, 3)numpy.ndarray An array whose columns represent the a, t and p components of a set of vectors in spherical coordinates.
- (
Notes
In Cartesian space, the components of each vector are defined as
\[\mathbf{v} = (v_x, v_y, v_z)\]In spherical coordinates, vectors are is defined as:
\[\mathbf{v^\prime} = (a, t, p)\]where
\(a\) is the amplitude of the vector
\(t\) is the azimuthal angle defined positive from vertical
\(p\) is the radial angle defined positive CCW from Easting
