Jama is a proposed interface standard for dense linear algebra computations. Jampack fully supports complex matrices. Developed by Pete Stewart of the University of Maryland and NIST, Jampack is preliminary and incomplete, but is being released to see if there is sufficient interest to continue its development. The beta release of Java Lapack is now available from the University of Tennessee at Knoxville. This code was automatically translated using f2j .
Some rudimentary documentation is available.
LinJa is a commercially supported linear algebra package for Java. It contains 25 classes and over 1000 methods for matrix and array operations, solving linear systems, computing eigenvalues, SVDs, complex numbers and some additional functions. OpsResearch has developed a freeware library of more than 450 Operations Research objects which include a complete implementation of the BLAS in both serial and parallel versions. Not meant for high-performance applications. Features include user settable or automatically scaled axes, automatically self-scaling time axes, labels as movable, customizable objects, and automatic generation of legends.
