sparsedd (sdd) is a substitute for the unix dd command which uses lseek(2) where possible when copying blocks of null bytes, in order to take advantage of the sparse storage implementation of the underlying filesystem.
JMatrixView is aJava/Swing matrix viewer. It works with Colt matrix implementation. It features dynamically tunable row/column resolution and has been designed for sparse matrix.
Save hundreds of developer hours with components built for SaaS applications.
The #1 Embedded Analytics Solution for SaaS Teams.
Whether you want full self-service analytics or simpler multi-tenant security, Qrvey’s embeddable components and scalable data management remove the guess work.
Sparse is a direct method solver for the large sparse matrices that are associated with electrical circuit simulation. It uses LU factorization and handles both real and complex square matrices.It is intended to solve many matrices with the same structure
An ANN design/implementation focused to work with optimally with NEAT (http://www.cs.utexas.edu/users/kstanley/neat.html). Semiann uses a sparse matrix to fill out the nodes, connections, weights, biases and activation functions for an ANN.
uBLAS is a C++ template class library that provides BLAS level 1, 2, 3 functionality for dense, packed and sparse matrices and many numerical algorithms for linear algebra.
A library providing basic building blocks for creating in-memory databases of important data. Existing components are: Linked lists; Hash tables with optional auto-resize; Memory-efficient sparse matrices built on hash tables; Red-black trees.
NOTE: This project is moving to Github; https://github.com/klmitch/dbprim
The goal of this project is to produce a genuinely Open Source multicast router that supports all existing multicast routing protocols. This will include DVMRP, PIM-2 (sparse and dense modes), MOSPF and BGMP.
MatGen is a matrix generator. It outputs matrices in MatrixMarket file format, taking as input a file describing the matrices´ properties. Currently it supports only random sparse matrices.
Blit contains a group of highly efficient iterative sparse solvers that can handle multiple right-hand-sides (i.e. block solvers). We will implement BLQMR, BLGMRES and other block algorithms in MATLAB, FORTRAN 90, C/C++, CUDA and OpenCL.
