la4j (Linear Algebra for Java) ![Build Status](https://camo.githubusercontent.com/d91e6e4f5ffd7a271e67f177841b87ab31921c551ddda9b12a042779dc193422/68747470733a2f2f7472617669732d63692e6f72672f766b6f737479756b6f762f6c61346a2e706e673f6272616e63683d6d6173746572)
Latest release (Dec 2012):
la4j - is open source and 100% Java library that provides Linear Algebra primitives and algorithms. There are the key features of la4j listed bellow:
- No dependencies and tiny size (~130kb jar)
- Simple and object-oriented/functional API
- Sparse (CRS, CCS) and dense (1D/2D arrays) matrices and vectors
- Linear systems solving (Gaussian, Jacobi, Zeidel, Square Root, Sweep and other)
- Matrices decomposition (Eigenvalues, SVD, QR, LU, Cholesky and other)
- Functors support: predicates, functions, procedures and accumulators
- MatrixMarket/CSV IO formats support
Brief Example
Matrix a = new Basic2DMatrix(new double[][] {
{ 1.0, 2.0, 3.0 },
{ 4.0, 5.0, 6.0 },
{ 7.0, 8.0. 9.0 }
});
Matrix b = a.invert(Matrices.DEFAULT_INVERTOR); // uses Gaussian Elimination
