A completely type-safe library for linear algebra http://noaxiom.org/tensor

Latest on Hackage:

This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

This library defines data types and classes for fixed dimension vectors and tensors. See the homepage http://noaxiom.org/tensor for more details, or Data.Tensor.Examples for a short tutorial.



- Prettified code.

Version 0.3.0

- New backend `Data.Tensor.Pure`.
- `QuickCheck` tests.
- Instance of `Applicative`.
- New method `generateM` in class `Tensor`, and new function `replicateM`.
- Removed classes: `FromVector` and `Zip` (use `liftA2` from `Applicative`).
- New class instances for `Tensor`: `Bounded`, `Random`.
- Removed `Ord` instances for `MultiIndex`es.
- Bug fixes and code improvements.

Version 0.2.0

- Added GHC.Generics support for `Cardinality` class.
- New classes: `Sliceable` in `Data.Tensor`, `Component`, `Extend` and
`HeadTail` in `Data.TypeList`, `Dimensions` in `Data.TypeList.MultiIndex`.
- Removed classes: `MatrixProduct` and `TensorProduct` from
- New functions: `elemMap` and `indexMap` in `Data.Tensor`.
- New method `split` in class `DirectSum` for splitting into the two components.
- New methods in class `SquareMatrix`: `polyEval` for evaluating a polynomial on
a matrix, and `minPoly` for computing the minimal polynomial.
- The methods `dimensions` in `Data.TypeList.MultiIndex` and `dims` in
`Data.Tensor` are replaced by the method `dimensions` of the new class
- Bug fixes and code improvements.
