12 Oct 2010 Inpaint over missing data in 1-D, 2-D, 3-D,... N-D arrays Y = INPAINTN(X) computes the missing data in the N-D array X. Author: Damien Garcia

I had to interpolate missing 3D geophysical data in order to enable standard filtration process. Inpaint code worked very well for this, the results look pretty well. Using inpaint is easy.
I recommend using this script also for other interested users.

On Matlab R2010a I always got the following warning message:
>> ANNI('my_m.in');
Warning: Directory access failure: my_fcn.m.
> In path at 110
In addpath at 87
In ANNI>init at 711
In ANNI at 39
fcn0 call: Time for preparing your problem for solution
fcn3 call: Here is the result (exact solution is x1 = -1, x2 = +1)
x1 = -1.0000 x2 = 1.0000
For details look into the file ANNI.log
******************************

There is some trouble with addpath command.

Hello Bohuslav,

just a few remarks regarding your ANNI solver:

1. in the README file is mentioned file "my_fcn.in" but in your package is file "my_m.in"

2. the example is extremely simple, could you add more complex example with user defined dimension and number of equations to give user chance to evaluate real performance figure?

Michal
