solve1|Click on the plot to select a point for
solve2|which the equations should be solved.
optim1|Click on the plot to select a point for
optim2|which the local minimum is computed.
regre1|Use the sliders to specify the number of
regre2|outliers. The best fit for the data is 
regre3|computed with two different methods.
polyn1|Use the sliders to describe the data and 
polyn2|degree of the polynomial to be fitted.
polyn3|The best fit polynomial is shown.
surfa1|Use the sliders to describe the data to
surfa2|be randomly generated. The best fit
surfa3|surface is shown.
