Google Scholar Digital Library. It offers high performance and low memory usage.

Sparse Matrices Matt Eding

Functionality similar to MATLAB and Octave.

Sparse matrix c++ library. The SparseMatrix class The class SparseMatrix is the main sparse matrix representation of Eigen s sparse module. View the project at CUSP Website and the cusp-users discussion forum for information and questions. LAPACK a C wrapper library for LAPACK and BLAS.

V051 April 28 2015 Linux Windows Coverage. A sparse matrix is a matrix in which majority of the elements are 0. Implementing sparse matrix-vector multiplication on throughput-oriented processors.

Since the number of zeroes is more than half the elements of the matrix it is a sparse matrix. Technical Report RC24704 IBM 2008. Dense and sparse matrices are supported Integer floating point and complex numbers are supported.

Sparse Basic Linear Algebra Subprograms BLAS Library This page contains software for various libaries developed at NIST for the Sparse Basic Linear Algebra Subprograms BLAS which describes kernels operations for sparse vectors and matrices. It uses MPI OpenMP and CUDA to support various forms of parallelism. Its written in Fortran and it is a pain to interface it with C.

The library is written in C and is callable from either C or Fortran program. Sparse Matrix Libraries in C Dense matrix support in C has been relatively good for some years thanks to The availability of optimized libraries with C bindings like LAPACK and BLAS which can be wrapped to implement the necessary algorithms The relative ease of working with directly indexed storage which makes writing algorithms simpler. An example for this is given as follows.

In our C sparse matrix library SparseLib the details of the underlying sparse matrix data format are completely hidden at the algorithm level. IT is a C library for linear algebra matrices and vectors signal processing and communications. The software package consists of matrix classes encompassing several sparse storage formats eg.

When it comes to large-scale sparse stuff I personally use the Harwell Subroutine library. IML is a C library for solving linear systems of equations capable of dealing with dense sparse and distributed matrices. These results in iterative algorithm codes which closely resemble their mathematical denotation.

Outline 1 General framework and motivation. A is the coefficient matrix with a dimension of nn and B is a vector of right hand side with a dimension of n the Spars Matrix A is like this see the figure I had a look though the Eigen document but I have a problem with defining and filling the Spars Matrix in C. Endgroup GoHokies May 11.

The templated class mapped_matrix is the base container adaptor for sparse matricies using element maps. A C Templated Sparse Matrix Library. Begingroup also the scipy sparse solvers use either SuperLU or UMFPACK so for a rm 10k times 10k sparse matrix with tilde 106 nonzeros a good CSuperLU implementation should match or at least come very close to scipys performance.

Google Scholar Digital Library. A C library which reads and writes sparse linear systems stored in the Harwell Boeing HB format for sparse matrices. The matrix given below contains 5 zeroes.

Optimizing sparse matrix-vector multiplication on gpus. I am trying to build a spars Matrix using a Eigen or Armadillo library in C to solve a system of linear equations Axb. Biomedical image analysis 2 The co-occurrence matrix and its computations 3 GPU platform and CUDA programming 4 Our GPU implementation on sparse matrices 5 Experimental results 6 Conclusions and future work Optimizing co-occurrence matrices on graphics processors 2 Igual et al.

SuperLU is a general purpose library for the direct solution of large sparse nonsymmetric systems of linear equations. Compressed row compressed column and coordinate formats and providing basic functionality. In SC pages 1--11 2009.

It implements a more versatile variant of the widely-used Compressed Column or Row Storage scheme. SparseLib is a C class library for efficient sparse matrix computations across various computational platforms. Useful for algorithm development directly in C or quick conversion of research code into production environments Provides efficient classes for vectors matrices and cubes.
