Courtesy of CRANberries, here is the diff to the previous release.0.2.25 2011-06-30 o Upgraded to Armadillo 2.0.1 which fixes two minor compilation issues 0.2.24 2011-06-29 o Upgraded to Armadillo release 2.0.0 "Carnivorous Sugar Glider" * faster multiplication of tiny matrices (≤ 4x4) * faster compound expressions containing submatrices * faster inverse of symmetric positive definite matrices * faster element access for fixed size matrices * added handling of arbitrarily sized empty matrices (eg. 5x0) * added loading & saving of matrices as CSV text files * added .count() member function to running_stat and running_stat_vec * added syl(), strans(), symmatu()/symmatl() * added submatrices of submatrices * det(), inv() and solve() can be forced to use more precise * algorithms for tiny matrices (≤ 4x4) * htrans() has been deprecated; use trans() instead * API change: trans() now takes the complex conjugate when transposing a complex matrix * API change: .is_vec() now outputs true for empty vectors (eg. 0x1) * API change: forms of chol(), eig_sym(), eig_gen(), inv(), lu(), pinv(), princomp(), qr(), solve(), svd(), syl() that do not return a bool indicating success now throw std::runtime_error exceptions when failures are detected * API change: princomp_cov() has been removed; princomp() in conjunction with cov() can be used instead * API change: set_log_stream() & get_log_stream() have been replaced by set_stream_err1() & get_stream_err1()
