I have the program as follows:
x = -2:0.2:2;
y = -2:0.2:3;
[X,Y] = meshgrid(x,y);
Z = X.*exp(-X.^2-Y.^2);
contour(X,Y,Z)
Now, I want to get a two-column matrix C that will give the (x,y) coordinates of a specific contour line, let us say for Z = 0.1. So, how to get this two-column matrix?

x = -2:0.2:2;
y = -2:0.2:3;
[X,Y] = meshgrid(x,y);
hold on % to your meshgrid a specific value for your contour.
[x1,y1] = contour(X,Y,Z,[0.1 0.1],'*k') % x1 will be your "two-column matrix"
