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.

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

Use in proprietary programs

You can use TooN in proprietary programs. TooN is under the same license as GCC's C++ standard library and GCC has been used extensively for proprietary programs.

TooN-1.1

If you still require TooN-1, the final version is now available. Use of this version is strongly discouraged since it makes extensive use of undefined behaviour and produces unreliable code on recent versions of GCC (>= 4.3.0). We will not be performing maintainance on this branch ourselves. However we will accept bug fixes or an offer to maintain the branch.
