Prev: reshape table to matrix while grouping rows

Hi,
I have a text file with three columns: x coordinate, y coordinate and the z value at point (x,y). I need to transfer this file to MATLAB and plot a 3D figure to show the z value at each point. How can I do this?
thanks,

Have you tried importing the data (using the GUI, or with the load command (Data=load([PathName FileName])), defining the variables (X=Data(:,1), Y=Data(:,2), Z==Data(:,3)), and using the mesh command (mesh(X,Y,Z)?
