Hi;
In main.c of v.surf.idw module in GRASS 6.0.1;
/* Arbitrary point to switch between searching algorithms. Could do
- with refinement PK /
if( (window.rowswindow.cols)/npoints > 400 )
is written to select old ( brute force ) or new (clarke) algorithm.
How did you decide the number 400? What is your test data or test function?
Do you have an article about that?
As much as I read from the articles whichs aouthor is Marc P. Armstrog Clarke’s algortihm is always better for different data sets.
Or is this a better way to define this number as an option for the user?
Best regards
Muzaffer…
