complex_2_quadrature

complex_2_quadrature(z)[source]

Take a complex number and returns quadrature, which is (length, arc-length from real axis).

Arc-length is calculated as \(|z| \arg(z)\).

Parameters:

z (number or array_like) – A complex number or sequence of complex numbers.

Returns:

mag (array like or scalar) – Magnitude (length).
arc_length (array like or scalar) – Arc-length from real axis: angle * magnitude.
