matrixFromVector :: Storable t => MatrixOrder -> Int -> Vector t -> Matrix t Source

unsafeFromForeignPtr

Arguments

:: Storable a
=> ForeignPtr a	pointer
-> Int	offset
-> Int	length
-> Vector a

O(1) Create a vector from a ForeignPtr with an offset and a length.

The data may not be modified through the ForeignPtr afterwards.

If your offset is 0 it is more efficient to use unsafeFromForeignPtr0.

unsafeToForeignPtr :: Storable a => Vector a -> (ForeignPtr a, Int, Int)

O(1) Yield the underlying ForeignPtr together with the offset to the data and its length. The data may not be modified through the ForeignPtr.

check :: String -> IO CInt -> IO () Source

check the error code

(//) :: x -> (x -> y) -> y infixl 0 Source

postfix function application (flip ($))

at' :: Storable a => Vector a -> Int -> a Source

access to Vector elements without range checking

atM' :: Storable a => Matrix a -> Int -> Int -> a Source
