Richard Franke's test data can now be downloaded from this site in the
same way as described below in this file, replacing the following part of the url
http://www.math.nps.navy.mil/~rfranke/
by
https://oleg-davydov.de/tsfit/Franke_test_data/
For example, for the MATLAB code of the famous Franke Test Function, open
https://oleg-davydov.de/tsfit/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.

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
f3.m Function 3 from NPS-53-79-001
f4.m Function 4 from NPS-53-79-001
f5.m Function 5 from NPS-53-79-001

fergo.m Ferguson's data, original
fergs.m Ferguson's data, scaled (y x 3)
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
moth1.m Moth data from Scientific American
moth2.m Moth data from Scientific American
sigmoid.m Sigmoid function
testdata.dat Compilation of all test data for NPS-53-79-001
vde200.dat F1 at 200 pts, density about proportional to curvature
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
vol-3t.dat vol-3.dat less some contours, 678 pts
vol3.m vol-3.dat as m-file
vol3t.m vol-3t.dat as m-file
vol87.dat Glacier contour data, 8345 points
Programs in pub/franke/sdprog
some are m-files, some are Fortran 77.
