Homework Statement

Printed text instructions: Develop the M file to draw the contour curve and surface together of the function f(x,y) = -xye^(-x^2-y^2) in the square defined -2 ≤ x ≤ 2 and 2 ≤ y ≤ 2. Also label all the axes and graph should have a title that includes your name. Publish your output to HTML.

Homework Equations

The Attempt at a Solution

MATLAB script showing linspace grids, meshgrid, z = -x*y*exp(-x.^2 - y.^2), contour(x,y,z), and xlabel, ylabel, zlabel calls.

look at line4, did I enter it correctly?
I must have did something wrong because there is no contour at all, all i see are parallel lines.

You are probably intending to use element-by-element multiplication, but you have used matrix multiplication. You need to use the .* operator instead.

You need to explain whether you solved the problem or not. It's now unclear whether you need help or not.
