Types
newtype MMatrix :: Nat -> Nat -> Type -> Type -> Type where Source #
A mutable matrix. See Matrix for
details about matrix layout.
type MMatrixXcf n m s = MMatrix n m s (Complex Float) Source #
Alias for single precision mutable matrix of complex numbers
type MMatrixXcd n m s = MMatrix n m s (Complex Double) Source #
Alias for double precision mutable matrix of complex numbers
type IOMatrix n m a = MMatrix n m RealWorld a Source #
A mutable matrix where the state token is specialised to RealWorld.
type STMatrix n m s a = MMatrix n m s a Source #
This type does not differ from MSparseMatrix, but might be desirable for readability.
Construction
new :: (PrimMonad p, Elem a, KnownNat n, KnownNat m) => p (MMatrix n m (PrimState p) a) Source #
Create a mutable matrix of the given size and fill it with 0 as an initial value.
replicate :: forall n m p a. (PrimMonad p, Elem a, KnownNat n, KnownNat m) => a -> p (MMatrix n m (PrimState p) a) Source #
Create a mutable matrix of the given size and fill it with an initial value.
Indexing
read :: forall n m p a r c. (PrimMonad p, Elem a, KnownNat n, KnownNat r, KnownNat c, r <= n, c <= m) => Row r -> Col c -> MMatrix n m (PrimState p) a -> p a Source #
Yield the element at the given position.
write :: forall n m p a r c. (PrimMonad p, Elem a, KnownNat n, KnownNat r, KnownNat c, r <= n, c <= m) => Row r -> Col c -> MMatrix n m (PrimState p) a -> a -> p () Source #
Replace the element at the given position.
Modification
set :: (PrimMonad p, Elem a) => MMatrix n m (PrimState p) a -> a -> p () Source #
Set all elements of the matrix to a given value.
copy :: (PrimMonad p, Elem a) => MMatrix n m (PrimState p) a -> MMatrix n m (PrimState p) a -> p () Source #
Copy a matrix.
Modification with Pointers
unsafeWith :: forall n m a b. (KnownNat n, KnownNat m, Elem a) => IOMatrix n m a -> (Ptr (C a) -> CInt -> CInt -> IO b) -> IO b Source #
Pass a pointer to the matrix's data to the IO action. Modifying dat through the pointer is unsafe if the matrix could have been frozen before the modification.
