Fetisch is a self-contained math library, primarily focusing on Linear Algebra and Symbolic Algebra.
- BigRational, a custom bigint-based rational primitive
- Permutation, an API for dealing with permutations
- Symbolic Algebra
- Expression Parser
- Expression Simplification
- Expression Matching and Manipulation API (like grep & sed for algebraic expressions)
- Numeric Calculator
- Linear Algebra:
- Matrix, supports any mxn matrices of any underlying field type (not just BigRational but also symbolic expressions)
- Matrix solver showing each step during transformation
- standard Matrix operations, such as
determinant,trace, and more. - and of course a
Vector<'T>
- LaTeX formatter
- Derivatives
- iterative determinant computation, so each computation step can be introspected (and even exported to LaTeX)
