cartesian_to_spherical

cartesian_to_spherical(x, y, z)

Convert cartesian coordinates to spherical coordinates.

Parameters:

• x (np.ndarray) –

  x coordinates

• y (np.ndarray) –

  y coordinates

• z (np.ndarray) –

  z coordinates

Returns:

• r( np.ndarray ) –

  r coordinates

• theta( np.ndarray ) –

  theta coordinates

• phi( np.ndarray ) –

  phi coordinates

clean_complex_to_db

clean_complex_to_db(array)

Calculates dB from an array of complex values.

Does some preprocessing of the input data to ensure no warnings are generated. Specifically, it replaces 0 magnitudes with a very small constant (1e-20).

Parameters:

• array (np.ndarray) –

  Array of complex values

Returns:

• np.ndarray –

  \(20 log_{10}(array)\)

spherical_to_cartesian

spherical_to_cartesian(r, theta, phi)

Convert spherical coordinates to cartesian coordinates.

Parameters:

• r (np.ndarray) –

  r coordinates

• theta (np.ndarray) –

  theta coordinates

• phi (np.ndarray) –

  phi coordinates

Returns:

• x( np.ndarray ) –

  x coordinates

• y( np.ndarray ) –

  y coordinates

• z( np.ndarray ) –

  z coordinates
