Conversion routines to take a surface (a function z of (x,y) or (theta,r)) and convert this into a solid; much as meshz does, but a little more useful for outputting as an STL for frabrication in a 3D printer. There are two cases, one in Cartesian co-ordinates, and the other in polar co-ordinates. Plus two sets of examples to show how they are used.

Faraz,
If you create folders called "Plots" and "STL" then the error will go away. The error is due to matlab not finding those folders on your computer.
