Surface plot of a math function

We would like to plot a function of two variables given by the math expression exp(-x^2 – y^2) * x.

The code is from the PGFPlots 1.10 manual: “3.5.4 Computing a Contour Plot of a Math Expression”.

Edit and compile if you like:
    title={$x \exp(-x^2-y^2)$}, 
    xlabel=$x$, ylabel=$y$,
	domain y=-1.3:1.3,
