      curve f(x;y) = 0 of the function f(x;y)=x3+y3−3xy. You can plot a single level curve of a function by using Matlab’s contourcommand in the form contour(x,y,z,[c c]). The following commands should produce an image similar to that in Figure 7. Note how a ner mesh is used in this example to improve the accuracy of the plot. >> [x,y]=meshgrid ...

      Using MATLAB, fit the same data to this new model, using the initial estimates C=10, a=2 . Because this equation is not a polynomial function, you cannot use polyfit, and will instead use a more generic minimization function called fminsearch (see hints at end). Plot the best model prediction and the data on the same plot.
