I have noticed another sort of unattractive behavior in trigrid.
Given an input set of points, I asked it to perform a linear
interpolation. The interpolation produced values that were
outside of the range of the input data. The magnitude of the
discrepancy increased as the number of points in the output
grid was increased.

I posted the details months ago, and got a resoundingly silent
response. I don't use trigrid because I don't trust what it is
doing. I am considering writing my own routine to do trigrid's job.

I would be thankful if anyone has details on the method that
trigrid is trying to implement. Sources of information on the
general topic of gridding/interpolation of random data would also
be of interest.
