Example used in Local optimization methods and software

In order to create a very simple example to test the fitting programs, we have create fake data in the interval [0,100] using a Gaussian shape following the formula:

Formula to create fake data

where R is a pseudo-random number in the interval [0,1] to simulate noise. We have created the data points using the parameteres A=[10.0,55.0,20.0]. The results of the fit (considering the noise) are A=[10.22,54.87,20.66].
A plot of the data points and a fit is here:
