NetLanders;

The Contour Routines is being posted through comp.sources.misc, look there
for the routines.

The contour routine is not big. It is actually quite small.
The key to using the routines is as follows:

        The routines expect the data to be upon some plane of coordinates x
and  y or whatever is being used. The random points are located within this
2d mesh of x and y points. The routine requires that 3 2d arrays should  be
present the first array is the location of the x point in mesh coordinates,
and so on. You can read about it in the Man page supplied.  This  could  be
used to do random point contouring by masking the unused coordinates within
the arrays with some value that you know the random values will not  touch.
Either way above the max or way below the minimun value of the function  to
be  plotted.  The  source and man page follow. It uses unix type plot calls
from a package developed here at Purdue (CRC  Graphics).  I  am  sure  your
system has a similiar package....Ed
