How can I plot 3D graph provided that I have x,y,z value

Hi,

If I want to plot 3-D graph featuring x,y, z...the value of which are known. Shall I use mesh command or is there anything easier to implement using data points I have in excel?

Many thanks in advance.

Hi,

if the data points x,y are irregular (i.e., not on some grid), just use plot3 to plot them. For functions like mesh and surf, you need to interpolate them to a grid, see http://www.mathworks.com/help/techdoc/math/bspq0rb-1.html.
