jblas is a fast linear algebra library for Java. It is based on BLAS and LAPACK, the de-facto industry standard for matrix computations, and uses state-of-the-art implementations like ATLAS for all its computational routines, making it very fast. It is essentially a lightweight wrapper around the BLAS and LAPACK routines. These packages originated in the Fortran community, which explains their archaic API. On the other hand, modern implementations are hard to beat performance-wise. jblas aims to make this functionality available to Java programmers such that they do not have to worry about writing JNI interfaces and calling conventions of Fortran code.
SourceSquare is a scanning solution based on Antepedia, a large open source knowledge base that includes more than 1,000,000 open source projects from the main forges. SourceSquare scans a folder on your hard drive and displays a tree map that shows which part of your source code is open source.
