Sparse matrix data structures, graphs, manipulation
1.A method for encoding a sparse matrix into a data structure, the data structure including a first array, the method comprising:receiving the sparse matrix;traversing a set of designated rows of the sparse matrix according to a deterministic sequence until all non-zero elements in the sparse ...

A hierarchic sparse matrix data structure for Hartree-Fock/Kohn-Sham calculations is presented. The data structure makes the implementation of matrix manipulations needed for large systems faster, easier, and more maintainable without loss of performance. Algorithms for symmetric matrix square and inverse...
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 ...
