[edit] Summary

Created by Kaushik Ghose using the MATLAB commands

A = 1; x0 = 0; y0 = 0; theta = 0; sigma_x = 1; sigma_y = 2; a = (cos(theta)/sigma_x)^2 + (sin(theta)/sigma_y)^2; b = -sin(2*theta)/(sigma_x)^2 + sin(2*theta)/(sigma_y)^2 ; c = (sin(theta)/sigma_x)^2 + (cos(theta)/sigma_y)^2;

[X, Y] = meshgrid(-5:.1:5, -5:.1:5); Z = A*exp( - (a*(X-x0).^2 + b*(X-x0).*(Y-y0) + c*(Y-y0).^2)) ; surf(X,Y,Z);shading interp;view(-36,36);axis equal;drawnow
