So I'm wanting to see in 3D the 2D guassian distribution with the pdf in the 3rd dimension. Hopefully this makes sense...

Anyway I'm trying something simple for R1n = 2x100 matrix containing 100 samples and 2 dimensions

    [X,Y]=meshgrid(R1n(1,:),R1n(2,:)); %form x-y plane
    Z=peaks(X,Y);
    plot3(X,Y,Z);

but am not even coming close? Any advice?
