If we assume I have a 1000x2 matrix generated using:

A = randn(1000,2);

How can I surface plot that A matrix to achieve a result similar to this image:

Is hist3 my only option? There isn't a way for me to match the exact layout of the example image I gave? I'm sure the example I gave used surf to plot its data.

A = randn(1000,2) ;

x = A(:,1) ; y = A(:,2) ;

x0 = min(x) ; x1 = max(x) ;

y0 = min(y) ; y1 = max(y) ;

m = 10; n = 10 ;

x = linspace(x0,x1,m) ;

y = linspace(y0,y1,n) ;

Z = hist3(A,'Nbins',[m n]) ;

surf(x,y,Z)

What does the data represent? X and Y coordinates of the points? If so where's the Z data?

Or do you have a long, thin sheet of paper and the data represents the height of points around the edges of that sheet?

x = [1 2 4 8; 0 3 3 9];

surf(x)
