Statistics.Matrix.Types

Basic matrix operations.

There isn't a widely used matrix package for Haskell yet, so we implement the necessary minimum here.

type Vector = Vector Double

type MVector s = MVector s Double

data Matrix

Two-dimensional matrix, stored in row-major order.

Constructors

Matrix

Fields

rows :: !Int

Rows of matrix.

cols :: !Int

Columns of matrix.

exponent :: !Int

In order to avoid overflows during matrix multiplication, a large exponent is stored separately.

_vector :: !Vector

Matrix data.

Instances

Eq Matrix

Show Matrix

data MMatrix s

Two-dimensional mutable matrix, stored in row-major order.

Constructors

MMatrix !Int !Int !Int !(MVector s)
