xy_to_z

pysmithchart.utils.xy_to_z(*xy)

Converts input arguments to a complex scalar or an array of complex numbers.

Parameters:

*xy (tuple) –

• If a single argument is passed:

  • If the argument is a complex number or an array-like of complex numbers, it is returned as-is.

  • If the argument is an iterable with two rows (e.g., shape (2, N)), it is interpreted as real and imaginary parts, and a complex array is returned.

• If two arguments are passed:

  • The first argument represents the real part (x), and the second represents the imaginary part (y).

  • Both arguments must be scalars or iterable objects of the same size. If they are iterable, they are combined to form a complex array.

Returns:

complex or numpy.ndarray – A complex scalar or array of complex numbers.
