Richard Franke's test data can now be downloaded from this site in the
same way as described below in this file.
For example, for the MATLAB code of the famous Franke Test Function, open
http://www.tsfit.de/Franke_test_data/sdprog/f1.m
As another example, the following file contains the 100 point data set
used in the report
R. Franke, A critical comparison of some methods for interpolation of
scattered data, Report NPS-53-79-003, Naval Postgraduate School, 1979.

as well as anonymous ftp mentioned below may not be available anymore.

This file is a copy of the README file on anonymous ftp under
ftp/pub/franke, except for this added prelude. To look at the
files I have available in sddata and sdprog subdirectories, see
the list below. To look at any of those files using your browser
here, just open, for example, the file
http://www.math.nps.navy.mil/~rfranke/sdprog/f1.m
If you have trouble accessing anything you need (or want), send
me an email with the problem.

I intend to have various things in here, eventually. For now there
are two subdirectories: sddata and sdprog
Data files in pub/franke/sddata
.m denotes a matlab m-file, some are functions,
some are "open" programs.
akima.m Akima's 60 points
bigsur.dat Water temperature data off Big Sur, 64 points
bigsur.m m-file for Big Sur water temperature data
ds1.m 25 point data set in NPS-53-70-003 (data set 3??)
ds2.m 33 point data set in NPS-53-70-003 (data set 2)
ds3.m 100 point data set in NPS-53-70-003 (data set 1??)
ds4.m 200 points: ds3 plus 100 based on curvature of f1
f1.m Function 1 from NPS-53-79-001
f2.m Function 2 from NPS-53-79-001

fhk500 500 points designed with functions kes1 and kes2 in mind
gniel.m Function from Nielson - IJNME 15(1978) 308-318.
kes1.m Function inspired by Salkauskas, p. 150 in Curve and Surface
Fitting, Lancaster and Salkauskas.
kes2.m Similar, to kes1, but "harder" to fit, perhaps.
mbay.dat Monterey Bay depth data - 1669 points

vde200.m same, as m-file
vde500.dat F1 at 500 pts, density about proportional to curvature
vde500.m same, as m-file
vol-3.dat Thinned section of vol87.dat, 873 pts
