Mantissa is a collection of various mathematical algorithms in Java aimed towards simulation. It features a small set of linear algebra classes, a least squares estimator, some curve fitting classes, several ordinary differential equation integrators (all supporting multiple switching functions and dense output), vectors and rotations in a three dimensional space, algebra-related classes like rational and double polynomials, various orthogonal polynomials, some optimization algorithms using direct search methods, and more. License: BSD License (revised) Changes: This release fixes an array update error in DummyStepInterpolator that could show up while serializing the interpolator despite having set up the step handler to not use continuous output.
