Manipulation on sparse data structure -- CFD Online Discussion Forums

June 26, 2001, 23:48	Manipulation on sparse data structure	#1
Takuya Tsuji Guest Posts: n/a	Dear all, once I asked about sparse matrix data structure on CFD ONLINE. http://www.cfd-online.com/Forum/main...cgi?read=16625 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?
