    -- * Basic types and data processing    
    module Numeric.HMatrix.Data,
    
    -- | The standard numeric classes are defined elementwise:
    --
    -- >>> fromList [1,2,3] * fromList [3,0,-2 :: Double]
    -- fromList [3.0,0.0,-6.0]
    -- 
    -- >>> (3><3) [1..9] * ident 3 :: Matrix Double
    -- (3><3)
    --  [ 1.0, 0.0, 0.0
    --  , 0.0, 5.0, 0.0
    --  , 0.0, 0.0, 9.0 ]
    --
    -- In arithmetic operations single-element vectors and matrices
    -- (created from numeric literals or using 'scalar') automatically
    -- expand to match the dimensions of the other operand:
    -- 
    -- >>> 5 + 2*ident 3 :: Matrix Double
    -- (3><3)
    --  [ 7.0, 5.0, 5.0
    --  , 5.0, 7.0, 5.0
    --  , 5.0, 5.0, 7.0 ]
    --

    -- * Products
    (<.>),
    
    -- | The matrix product is also implemented in the "Data.Monoid" instance for Matrix, where
    -- single-element matrices (created from numeric literals or using 'scalar')
    -- are used for scaling.
    --
    -- >>> let m = (2><3)[1..] :: Matrix Double
    -- >>> m <> 2 <> diagl[0.5,1,0]
    -- (2><3)
    -- [ 1.0,  4.0, 0.0
    -- , 4.0, 10.0, 0.0 ]
    --
    -- mconcat uses 'optimiseMult' to get the optimal association order.
