[Haskell-cafe] Matlab Style Logic Operations ala V1.*(V2>0) on Vectors and Matrices with HMatrix ??

Thanks for the help on the typing issue, that helped my understanding a lot. 

Regarding the lift2 Matrix: 

this line works :

matrixfunction x y = liftMatrix2 (zipVectorWith(\a1 a2 -> if a2>=0 then a1
else 0)) x y 

but when I use this line : 

matrixfunction f x y = liftMatrix2 (zipVectorWith f) x y 

how can / do I have to define f in a seperate line a way, that it works and
gives the same result ?

Cheers Phil
