Data.Matrix.Dense.IO

Mutable dense matrices in the IO monad.

The IOMatrix data type

data IOMatrix np e

Dense matrix in the IO monad. The type arguments are as follows:

• np: a phantom type for the shape of the matrix. Most functions will demand that this be specified as a pair. When writing a function signature, you should always prefer IOMatrix (n,p) e to IOMatrix np e.
• e: the element type of the matrix. Only certain element types are supported.
