module Numeric.LinearAlgebra (
-- * Basic types and data processing
module Numeric.LinearAlgebra.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 ]
--
-- * Matrix product
(<.>),
-- | This operator can also be written using the unicode symbol ◇ (25c7).
--
-- | The matrix x matrix product is also implemented in the "Data.Monoid" instance, 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.
