Is a matrix is a linear operation on a vector,

It _is_ not a linear map, but it is a canonical representation of a linear map.

does it not make sense to define matrix applicaion:

mapply :: Matrix -> Vector -> Vector

Then you can define say:

rotate90 = mapply rotationMatrix90

v' = rotate90 v

... that's what I said about mulVec.
