sqrt_phase_unwrap

pmrf.math.sqrt_phase_unwrap(z: Array | ndarray | bool | number | bool | int | float | complex)

Take the square root of a complex number with unwrapped phase.

This idea came from Lihan Chen.

\[\sqrt{|z|} \exp( \arg_{unwrap}(z) / 2 )\]

Parameters:

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

Returns:

z – A complex number or sequence of complex numbers.

Return type:

number of array_like
