This is the change log for the Ada 2005 Math Extensions project (https://sourceforge.net/projects/gnat-math-extn/) on SourceForge. 20130529 Packages Ada_Numerics.Float_Arrays and .Long_Float_Arrays are provided; they are instantiations of .Generic_Arrays for the standard Float and Long_Float types. The packages are declared Pure. The code is compatible with GNAT GPL 2013 (a minor change was required to avoid a compilation warning). 20120712 The GNAT Project file is now in the top directory of the distribution. The tests expect AUnit to be installed. Different releases of LAPACK may alter the sign of eigenvectors returned by the generalized eigensystem code (remember that the generalized eigensystem is Av = lBv, where l is an eigenvalue and v is the corresponding eigenvector). This only affected the tests. Testing on Debian 6 required an increase in the test limit for complex general eigenvalues tests for Float. In GNAT GPL 2012 and GCC 4.7, LAPACK and BLAS are no longer used, and therefore aren't provided as part of GNAT on platforms where they aren't natively available. This package requires LAPACK and BLAS to be installed (it links with "-llapack -lblas"). 20110320 An additional overloaded procedure Eigensystem returns the generalized eigenvalues and eigenvectors of a pair of non-hermitian complex matrices. The program Test_Extensions is renamed to Demo_Extensions, and includes a demonstration of the real generalized eigensystem code. The library project file is renamed src/gnat_math_extensions.gpr. 20101223 The package is renamed to Ada_Numerics.Generic_Arrays. An additional overloaded procedure Eigensystem returns the generalized eigenvalues and eigenvectors of a pair of non-symmetric real matrices. 20100901 An additional overloaded procedure Eigensystem returns the complex eigenvalues and eigenvectors of a non-symmetric real matrix. 20100818 An additional overloaded function Eigenvalues returns the complex eigenvalues of a non-symmetric real matrix. Procedure Eigensystem returns the complex eigenvalues and eigenvectors of a non-hermitian complex matrix. The package is renamed to Ada.Numerics.Generic_Arrays. 20100810 This is the first release. There is only one operation: the function Eigenvalues returns the eigenvalues of a general (non-Hermitian) complex matrix.
