linearComb :: C a v => [a] -> [v] -> vSource

Compute the linear combination of a list of vectors.

ToDo:
Should it use `NumericPrelude.List.Checked.zipWith`

?

integerMultiply :: (C a, C v) => a -> v -> vSource

This function can be used to define any
`C`

as a module over `Integer`

.

Better move to Algebra.Additive?
