Default Manipulation on sparse data structure
Takuya Tsuji
Posts: n/a
Dear all, once I asked about sparse matrix data structure on CFD ONLINE.

Thanks to contributors, I understand the "triad format" And existance of sparse linear solver/library. But please let me ask again. I need element-by-element manipulation on sparse representation because I'm using for finite difference.

In case of "triad format", Searching for a element from all data is needed. I think this is inefficient particularly. Do you know any idea? "Triad Format" doesn't suit in this case?
