Documentation
Mutable matrix. You can modify elements
type MMatrixXcf = MMatrix (Complex Float) (CComplex CFloat) Source #
Alias for single previsiom mutable matrix of complex numbers
type MMatrixXcd = MMatrix (Complex Double) (CComplex CDouble) Source #
Alias for double prevision mutable matrix of complex numbers
Construction
new :: (PrimMonad m, Elem a b) => Int -> Int -> m (MMatrix a b (PrimState m)) Source #
Create a mutable matrix of the given size and fill it with 0 as an initial value.
replicate :: (PrimMonad m, Elem a b) => Int -> Int -> a -> m (MMatrix a b (PrimState m)) Source #
Create a mutable matrix of the given size and fill it with as an initial value.
Consistency check
Accessing individual elements
read :: (PrimMonad m, Elem a b) => MMatrix a b (PrimState m) -> Int -> Int -> m a Source #
Yield the element at the given position.
write :: (PrimMonad m, Elem a b) => MMatrix a b (PrimState m) -> Int -> Int -> a -> m () Source #
Replace the element at the given position.
unsafeRead :: (PrimMonad m, Elem a b) => MMatrix a b (PrimState m) -> Int -> Int -> m a Source #
Yield the element at the given position. No bounds checks are performed.
unsafeWrite :: (PrimMonad m, Elem a b) => MMatrix a b (PrimState m) -> Int -> Int -> a -> m () Source #
Replace the element at the given position. No bounds checks are performed.
Modifying matrices
set :: (PrimMonad m, Elem a b) => MMatrix a b (PrimState m) -> a -> m () Source #
Set all elements of the matrix to the given value
copy :: (PrimMonad m, Elem a b) => MMatrix a b (PrimState m) -> MMatrix a b (PrimState m) -> m () Source #
Copy a matrix. The two matrices must have the same size and may not overlap.
unsafeCopy :: (PrimMonad m, Elem a b) => MMatrix a b (PrimState m) -> MMatrix a b (PrimState m) -> m () Source #
Copy a matrix. The two matrices must have the same size and may not overlap however no bounds check performaned to it may SEGFAULT for incorrect input.
