Quantity/Formatter Library is a Java library developed in accordance to the quantity/formatter pattern (as demonstrated by the Date/SimpleDateFormat in the standard J2SE library). The following quantity/formatter pairs are currently available: Currency/CurrencyFormat, Density/ DensityFormat, Dimension/DimensionFormat, Distance/ DistanceFormat, ElapsedTime/ElapsedTimeFormat, Temperature/TemperatureFormat, Volume/VolumeFormat, and Weight/WeightFormat.
LAPLib (Linear Algebra Performance Library) is an object-oriented software library which provides an elegant interface to access the optimized performance of these old-style libraries. LAPLib transparently handles all low-level details concerned with invocation of BLAS and LAPACK functions. Using LAPLib, developers can write expressions in a C++ object-oriented fashion and greatly reduce the complexity associated with using BLAS and LAPACK routines while maintaining excellent performance.
