What is the difference between these commands ?

can anyone tell me the difference between plot3 and meshgrid and surf ?

Answer 1

plot3() plots some markers at the specified points. It does not make a solid surface between the markers.

surf() will create a solid surface between the points.

meshgrid() gives every possible combination of every x and every y. It is not a plotting function.

There are examples in the help. Did you try any or all of them? I'm attaching a demo fro make a movie from the surf() command.
