Release Notes: This release contains faster inverse of matrices marked as diagonal and faster transpose of sparse matrices. It also has more efficient handling of aliasing during matrix multiplication.
Release Notes: This release contains faster handling of sparse submatrix views and better code generation when using the Clang C++ compiler. It also contains a workaround for a bug in LAPACK 3.4.
Release Notes: This release adds eigen decompositions of sparse matrices and a MEX connector for interfacing Matlab and Octave with Armadillo matrices. Many decompositions now use faster divide-and-conquer methods by default.
Release Notes: This release adds divide-and-conquer variants of economical SVD and pseudo-inverse functions, element-wise variants of min() and max(), easier specification of submatrix view sizes, and a more precise timer when using C++11.
Release Notes: This release adds functions for 2D fast Fourier transform and various speedups when using C++11.
Release Notes: This release has faster multiplication of matrices with their corresponding transposes. It also adds functions for indicating presence of elements satisfying relational conditions.
Release Notes: This release adds automatic SIMD vectorization (e.g., SSE2) of elementary expressions when using GCC 4.7+ with -O3 optimization. It also adds faster handling of compound expressions with vector transposes, as well as saving of cubes in HDF5 format.
Release Notes: This release has various speedups for handling of small vectors and fixed-size matrices.
Release Notes: This release adds a faster find() function. It als contains a fix for non-contiguous submatrix views to handle empty vectors of indices.
Release Notes: This release adds a faster determinant operation for diagonal and triangular matrices. It also contains more fine-grained handling of 64 bit integers.
