Meshgrid and contours
A common task is a graphical representation of a scalar function over a rectangle:
For this, first we have to generate a grid on the rectangle [a,b] x [c,d]. This is done using the meshgrid command:
n = ... # number of discretization points along the x-axis m = ... # number of discretization points along the x-axis X,Y = meshgrid(linspace(a,b,n), linspace(c,d,m))
X and Y are arrays with (n,m) shape such that 
contains the coordinates of the grid point as shown in the next figure (Figure 6.6):
Figure 6.6: A rectangle discretized ...
