gaussian returns the value of the gaussian function:

f = (1 / (sigma * sqrt(2pi))) * exp(-0.5 * (x / sigma)**2)

r = gaussian(x : float,fwhm : float)

Variable	Type	Description
x	float	Value at which the function is evaluated.
fwhm	float	Full width at half maximum; *fwhm = 2 sqrt(2ln2) sigma**
r	tuple	The tuple returned by the function. r[0] : int, error code. If non-zero, an error has occurred. r[1] : str, error message. r[2]: float, value of the function at x.

Variable

Type

Description

float

Value at which the function is evaluated.

fwhm

float

Full width at half maximum; fwhm = 2 * sqrt(2*ln2) * sigma

tuple

The tuple returned by the function.

r[0] : int, error code. If non-zero, an error has occurred.

r[1] : str, error message.

r[2]: float, value of the function at x.
