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.
