Hello,

I need help shifting the center of a bivariate distribution. Using MATLAB's example,

mu = [0 0];
Sigma = [0.25 0.3; 0.3 1];
x1 = -3:0.2:3;
x2 = -3:0.2:3;
[X1,X2] = meshgrid(x1,x2);
X = [X1(:) X2(:)];
y = mvnpdf(X,mu,Sigma);
y = reshape(y,length(x2),length(x1));
figure(1)
surf(x1,x2,y)
% caxis([min(y(:))-0.5*range(y(:)),max(y(:))])
% axis([-3 3 -3 3 0 0.4])
xlabel('x1')
ylabel('x2')
zlabel('Probability Density')

I would like to shift this distribution to a new center of (2,2). As of now, it's centered at (0,0).

I know that this could be done during the plotting of the distribution. But I would like to shift the entire distribution utilizing the same x1 and x2 arrays.
