TooN: Tom's Object-oriented numerics library

TooN is a C++ numerics library which is designed to operate efficiently on large numbers of small matrices, and provides easy access to a number of algorithms including matrix decompositions and optimizations.

TooN is type generic and will work very well

It is designed to integrate very will with the libCVD computer vision library and GVars3 configuration library. Miscellaneous extra algorithms are available in TaG

News

18/02/2013: Version 2.1 released. Changes:
- Built in unpivoted type generic QR factorisation using Householder reflections.
- swap now swaps Vector efficiently.
- 2x2 Matrix inverse function.
- Lots of conistency improvements (more general DiagonalMatrix, optimizations defaulting to Dynamic, construct Vector from Data, FADBAD++ improvements).
- More extensive regression tests.
- Fixed some numerical bugs in 2x2 and 3x3 SymEigen .
- Platform compatibility improvements (VS2010, regression tests with non GNU AWK).
02/12/2012: Automatic regression testing on drone.io
22/11/2012: Moved to github.
08/02/2012: Version 2.0 released (after nearly 3.5 years in beta and it's cleaner, more general, more fully featured and smaller than TooN 1). Changes since Beta_8
- Matrix square root.
- Matrix logarithm and SL<>::ln()
- Sim(2) and Sim(3) groups
- fadbad++ integration with SO(3) and SE(3)
- CLAPACK compatibility
Notable bugfixes and cleanups since Beta_8
- More consistent use of Precision and DefaultPrecision
- More consistent fadbad++ integration
- Various platform fixes (especially MinGW and clang++)
- More general operators for group objects
- Fixed out of bounds error in builtin SVD
06/02/2012: Switched source repository to git
03/11/2010: Released Version 2.0 Beta 8
