surfi

02 Nov 2004 (Updated 29 Nov 2004)

Code covered by the BSD License

plot (or return) surface interpolated from supplied vertices.

File Information
Description	i often need to visualise a surface formed by a set of vertices when those vertices are not on a regular grid. surf() won't do this, so i made this file to generate the surface then plot it. the suffix `i' refers to interpolate. i'm not sure if the R14 surf function can do this, i couldn't work out the syntax - if it can, perhaps someone can post a comment with the syntax, and i'll withdraw this submission. also included is triangulate (a port from third party code, see help for details), which returns the surface without plotting it. source for this is included, and a binary for R14 under XP - you will need to compile for use on other platforms. UPDATE: note that you will need to sort vertices before passing them to the function if they are not already sorted - see the demo for details.
MATLAB release	MATLAB 7 (R14)
Other requirements	should be ok on 6.5, and probably 6, but untested. if not running under XP R14, you may need to recompile. if not running under Windows, you will need to recompile.
