In the next example, we show how complex-valued residual functions of complex variables can be optimized with least_squares(). Consider the following function: >>>

Find a root of a real or complex function using the Newton-Raphson (or secant or Halley's) method. toms748 (f, a, b[, args, k, xtol, rtol, ...]) Find a root using TOMS Algorithm 748 …

Jan 18, 2015 · scipy.optimize.curve_fit(f, xdata, ydata, p0=None, sigma=None, absolute_sigma=False, check_finite=True, **kw) [source] ¶ Use non-linear least squares to fit …

In case the sequence x is complex-valued, the spectrum is no longer symmetric. To simplify working with the FFT functions, scipy provides the following two helper functions. The function …

Jun 10, 2017 · Alternatively, what kind of array scalar is present can be determined using other members of the data type hierarchy. Thus, for example isinstance(val, np.complexfloating) will …

The Hilbert transform constructs the complex-valued analytic signal from a real signal. For example, if \(x=\cos\omega n\) , then \(y=\textrm{hilbert}\left(x\right)\) would return (except near …
