Functions

aare.gaus(x: numpy.ndarray[numpy.float64], par: numpy.ndarray[numpy.float64]) → numpy.ndarray

Evaluate a 1D Gaussian function for all points in x using parameters par.

Parameters:

  • x (array_like) – The points at which to evaluate the Gaussian function.

  • par (array_like) – The parameters of the Gaussian function. The first element is the amplitude, the second element is the mean, and the third element is the standard deviation.

aare.pol1(x: numpy.ndarray[numpy.float64], par: numpy.ndarray[numpy.float64]) → numpy.ndarray

Evaluate a 1D polynomial function for all points in x using parameters par. (p0+p1*x)

Parameters:

  • x (array_like) – The points at which to evaluate the polynomial function.

  • par (array_like) – The parameters of the polynomial function. The first element is the intercept, and the second element is the slope.
