WebFunction for detecting local maxima and minima in a signal. Discovers peaks by fitting the model function: y = A * sin (2 * pi * f * (x - tau)) to the peaks. The amount of points used. in the fitting is set by the points argument. Omitting the x_axis is forbidden as it would make the resulting x_axis.
