Statistics.Matrix.Mutable

Basic mutable matrix operations.

Synopsis

datadata MMatrix s

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

typetype MVector s = MVector s Double

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

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

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

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

valueunsafeNew

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

valueunsafeFreeze :: MMatrix s -> ST s Matrix

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

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

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

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

valueunsafeBounds :: 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.
