Ciao Fabio,

The error is exactly what the error message says, on line 19 of HaltonProva.m 
you have:

hh = FillDistance(xh,yh)

but FillDistance is neither a vector that can be indexed as FillDistance(…)  
nor a function that takes input arguments in parentheses, but rather a script 
file, 
so this line makes no sense.

BTW, if your file FillDistance.m is really as you wrote it:

%%% FillDistance.m

hX = FillDistance(x,y)
neval = 40;
grid=linspace(0,1,neval);
[xe,ye]=meshgrid(grid);
epoints=[xe(:) ye(:)];
ctrs=[x y];
DM_eval=DistanceMatrix(epoints,ctrs);
hX=max(min(DM_eval'));

there is something very wrong with your code as the script FillDistance is also 
trying to invoke itself as a function …
Where did you get this code from?
