17 Nov 2011 Mesh Laplacian Interpolation Operator Computes the zero Laplacian interpolation matrix Author: Darren Weber Timothy

This program is a hidden gem. I am able to interpolate on a meshed surface with an index of scalar values.

The only problem that I was running into (I wrote a code for it) is that the program sorts the nodes list but does not keep the scalar value for the specified nodes. Example of this: 2 3 1 have values of 0.3 0.2 and 0.5, the list is sorted as 1 2 3, but the values remain as 0.3 0.2 0.5 and not 0.5 0.3 0.2. Also when removing the same points, you also need to remove the reiterated scalar values.

Thank you very much. Great Code, saved lot of time.

Hi,

I've found that
"hist.exp_time = sprintf('%2d-%2d-%2.0f',datime(4),datime(5),datime(6));"
doesn't make up the 10 bytes required, so I had to modify it to "%2.1f". But sometimes I still get a 347 byte hdr file. I'm not quite sure why that happens...

Thanks for these programs, I would never have been able to do this from scratch.

Extremely well made. Finding these files has saved me 2 weeks of programming.
