Basic mutable matrix operations.

Documentation

data MMatrix s

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

Constructors

MMatrix !Int !Int !(MVector s)

type MVector s = MVector s Double

replicate :: Int -> Int -> Double -> ST s (MMatrix s)

thaw :: Matrix -> ST s (MMatrix s)

bounds :: MMatrix s -> Int -> Int -> (MVector s -> Int -> r) -> r

Given row and column numbers, calculate the offset into the flat row-major vector.

unsafeNew

Arguments

:: Int

Number of row

-> Int

Number of columns

-> ST s (MMatrix s)

Allocate new matrix. Matrix content is not initialized hence unsafe.

unsafeFreeze :: MMatrix s -> ST s Matrix

unsafeRead :: MMatrix s -> Int -> Int -> ST s Double

unsafeWrite :: MMatrix s -> Int -> Int -> Double -> ST s ()

unsafeModify :: MMatrix s -> Int -> Int -> (Double -> Double) -> ST s ()

immutably :: NFData a => MMatrix s -> (Matrix -> a) -> ST s a

unsafeBounds :: MMatrix s -> Int -> Int -> (MVector s -> Int -> r) -> r

Given row and column numbers, calculate the offset into the flat row-major vector, without checking.
