Hi everyone,
I'm trying to show a graphics of functions. So, with function with one
minimum, the plot is ok, but with some functions with two minimum, the
graphic doesn't represent the function. Below is my code:
%------------------------------------------------------
x = y = -10:0.1:10;
[x, y] = meshgrid(x, y);
z = (x - 1).^2 * (x - 2).^2 + (y - 1).^2;
mesh(x, y, z);
%------------------------------------------------------
The output:

The output expected:
