About: Armadillo is a template C++ linear algebra library aiming towards a good balance between speed and ease of use. Matrix decompositions are provided through optional integration with LAPACK, or one of its high performance drop-in replacements (eg. Intel MKL).

• added fast Fourier transform
• added handling of .imbue() and .transform() by submatrices and subcubes
• added batch insertion constructors for sparse matrices
• minor fix for multiplication of complex sparse matrices
• better detection of recent Intel MKL versions during installation

About: The Universal Java Matrix Package (UJMP) is a data processing tool for Java. Unlike JAMA and Colt, it supports multi-threading and is therefore much faster on current hardware. It does not only support matrices with double values, but instead handles every type of data as a matrix through a common interface, e.g. CSV files, Excel files, images, WAVE audio files, tables in SQL data bases, and much more.
