Numerical Search for Extremum Points in a Square Domain to Find Local Maxima and Minima of a 2D Function f(x,y)
Drag point B to generate contour lines. Their patterns will help you locate the local extrema of the function f(x,y).
Move point A to display the nxo points of the square with side length ao on the surface of the function f(x,y). Below the plot on the left side, you will find the corresponding coordinates, as well as the maximum and minimum values of the function among these points (Rmax and Rmin) .
