insertRowWith :: (IxCol -> IxCol) -> SpMatrix a -> SpVector a -> Key -> SpMatrix a Source #
Insert row , using the provided row index transformation function
insertColWith :: (IxRow -> IxRow) -> SpMatrix a -> SpVector a -> IxCol -> SpMatrix a Source #
Insert column, using the provided row index transformation function
diagonalSM :: SpVector a -> SpMatrix a Source #
Fill the diagonal of a SpMatrix with the components of a SpVector
lookupRowSM :: SpMatrix a -> IxRow -> Maybe (SpVector a) Source #
Lookup a row in a SpMatrix; returns an SpVector with the row, if this is non-empty
extractCol :: SpMatrix a -> IxCol -> SpVector a Source #
Extract jth column
extractRow :: SpMatrix a -> IxRow -> SpVector a Source #
Extract ith row
extractVectorDenseWith :: Num a => (Int -> (IxRow, IxCol)) -> SpMatrix a -> SpVector a Source #
Generic extraction function
extractSubRow :: SpMatrix a -> IxRow -> (Int, Int) -> SpVector a Source #
extract row interval (all entries between columns j1 and j2, INCLUDED, are returned) extractSubRow :: SpMatrix a -> IxRow -> (IxCol, IxCol) -> SpVector a extractSubRow m i (j1, j2) = case lookupRowSM m i of Nothing -> zeroSV (ncols m) Just rv -> ifilterSV (j _ -> j >= j1 && j <= j2) rv
", returning in Maybe extractSubRow :: SpMatrix a -> IxRow -> (Int, Int) -> Maybe (SpVector a) extractSubRow m i (j1, j2) = resizeSV (j2 - j1) . ifilterSV (j _ -> j >= j1 && j j2) <$ lookupRowSM m i
Extract an interval of SpVector components, changing accordingly the resulting SpVector size. Keys are _not_ rebalanced, i.e. components are still labeled according with respect to the source matrix.
extractSubCol :: SpMatrix a -> IxCol -> (IxRow, IxRow) -> SpVector a Source #
extract column interval
extractSubRow_RK :: SpMatrix a -> IxRow -> (IxCol, IxCol) -> SpVector a Source #
extract row interval, rebalance keys by subtracting lowest one
extractSubCol_RK :: SpMatrix a -> IxCol -> (IxRow, IxRow) -> SpVector a Source #
extract column interval, rebalance keys by subtracting lowest one
fromRowsV :: Vector (SpVector a) -> SpMatrix a Source #
Pack a V.Vector of SpVectors as rows of an SpMatrix
fromColsV :: Vector (SpVector a) -> SpMatrix a Source #
Pack a V.Vector of SpVectors as columns of an SpMatrix
toRowsL :: SpMatrix a -> [SpVector a] Source #
Unpack the rows of an SpMatrix into a list of SpVectors
toColsL :: SpMatrix a -> [SpVector a] Source #
Unpack the columns of an SpMatrix into a list of SpVectors
