Description

Thanks to financial support from ​http://mpba.fbk.eu/en/home , I have implemented equal split algorithm on network as described in "A kernel density estimation method for networks, its computational method and a GIS-based tool, Okabe et. all, 2009" and new kernel density functions in both 1 and 2 D: uniform, triangular, epanechnikov, quartic, triweight, cosine

Vector network library improvement was necessary, the patch includes cache bug fix. The patches are against 6.4.0.

Cool. Could you also provide patches against current 6.4.1? BTW, the cache is working in 6.4.1, but not in 6.4.0, and only patches against 6.4.1 can be included in the current release branch. I could help in forward porting the changes to 6.5 and 7.0.

Patches applied in trunk r45393. I took the liberty to also update the manual.

Radim, could you please review? Thanks!

Thank you a lot. I forgot about the manual completely. I'll look at it ASAP.

The manual is perfect, I could not write it better.

Thank you again. Radim

Milestone: 6.4.1 → 6.4.2

Changing milestone to 6.4.2. Maybe time to backport to devbr64 and after 6.4.1 release to relbr64?

Backported to devbr in r45407. IMHO, the documentation is still a bit thin. There is also potential to speed up the whole module, but that's something that should be left for trunk.
