MATLAB Multivariate Interpolation Toolbox
This toolbox contains code for 2D multivariate interpolation in MATLAB.
- Adaptive Normalised Convolution (ANC)
- Radial Basis Function Interpolation (RBF)
- Natural Neighbour Interpolation
- The included Natural Neighbours interpolation software was provided by Pavel Sakov and is available at URL: http://www.marine.csiro.au/~sakov/nn.tar.gz

Some functions require MEX functions to built. To compile all of the necessary
Makefiles in UNIX, type
make. Some of the Makefiles may require alterations
for your system, however, provided you have a complete build environment, and
mexext are available, the process should be fairly
simple. You should then find a directory named
toolkit. Copy this directory somewhere in your MATLAB work area, and finally, from within MATLAB, issue the command:
It is not necessary to use
genpath, or include the
With the exception of ANC, which interpolates onto matrices, all of the functions provided have prototypes of the following form:
[xx, yy, zz] = function(xi, yi, zi, xx, yy, [optional args])
or more simply
zz = function(xi, yi, zi, xx, yy, [optional args])
The help within the various functions gives more information on the input and output arguments. For example, issuing the command:
Will print the built in help for the RBF interpolation command.
Running the command:
interpolation_toolkit is the directory name, will give basic help for the toolkit, including some usage instructions.
ANC operates using matrices, and requires arguments of the following form:
out = adaptiveNC(si, cm, [optional args])
Full help is available within the m-file.
