ASHAPE is a simple wrapper for ASLIB, which implements several (optimized) subroutines to extract and display 2d alpha shapes and alpha patches from a set of x/y data points

ASLIB returns a structure, which contains all relevant parameters, data and results including graphics handles to plotted elements

furthermore, ASLIB returns function handles to all of its computational and graphics subroutines, which can be used by a programmer to create more elaborate wrappers or guis

the latest version of ASLIB can always be attached to an existing set of parameters p by
> p.f = aslib;
or by simply re-running the data
> p = ashape(p);

for general instructions see:
> help ashape
> help aslib
for explanations of subroutines and a small glossary of terms see:
> aslib -s
for explanations of fields see:
> aslib -f
for explanations of options see:
> aslib -o

look at the accompanying published m-file for a few examples
