Plotting 3D scatter plot from elements in a matrix

Hello all,

I have a matrix A with dimensions 47 x 4. I would like to plot the values in the matrix in a 3D plot. For e.g element A(4, 5) = 12 should be represented with x=4, y=5 and z= 12. Since, the values are non-uniform, I think a 3D scatter plot would be a good way to visualize the data. But, I tried mesh as well as surf to represent the data but the figure obtained was weird. Something like following. Could someone please help me converting this to a 3D scatter plot.

m = randi(100,47,4);   % Here is your (fake) 47x4 data

[x ,y] = ndgrid(1:size(m,1),1:size(m,2));     % produce x and y coordinates
plot3(x(:),y(:),m(:), 'o')                    % plot it
grid on                                       % turn on the grid (optional, of course)

Thank you very much. At least I got the idea of how to go about approaching such cases.
