Yes I'd like do do this for roughly 500,000 d_i. I'm solving a diffusion problem, I only have local measures of the diffusion process which is what i use to determine that matrix M. Now the 500,000 d_i are the boundaries to my diffusion problem, what i need to know is who much of what gets pumped in though a given boundary state exits the system through the other boundaries. Do i really need to do all 500,000 Probably not. this is the highest resolution mesh of the boundary i can compute from my data. A lower res mesh would probably be sufficient. But I wont know until i do it either way I'd like to use the highest res mesh that I can. If you can suggest an alternative approach I am all ears. Luke >>> 2.
