- FLENS - a flexible library for efficient numerical solutions
FLENS is a C++ numerical library for research (efficient) and teaching (convenient usage). Centered around flexible and high performance matrix and vector types (dense/sparse, finite/infinite) several solvers for linear equations and other algorithms are provided. The iterator concept facilitates integration with STL algorithms.
An Artificial Intelligence
This is an artificial intelligence that has the ability to see patterns within chaos. We have been applying it to the stock market and have future plans to sell subscriptions to view those results. But now we wish to apply it to simpler situations which may help small businesses improve their efficiency.
