watex.utils.exmath.fitfunc(x, y, deg=None, sample=1000)[source]#

Create polyfit function from a specifc sample data points.

Parameters:

  • x – array-like of x-axis.

  • y – array-like of y-axis.

  • deg – polynomial degree. If None should compute using the length of extrema (local + global).

  • sample – int - Number of data points should use for fitting function. Default is 1000.

Returns:

  • Polynomial function f

  • new axis x_new generated from the samples.

  • projected sample values got from f.
