	Func<Vector<T>^, U>^ function, 
	Vector<U>^ result
)

member ReduceColumnsInto : 
        function : Func<Vector<'T>, 'U> * 
        result : Vector<'U> -> Vector<'U>

function Func<Vector<T>, U>: A delegate that represents a multivariate function.
result Vector<U>: The vector that is to hold the result.

Vector<U>
A Vector<T> whose elements are the result of applying function to each column of the matrix.

The length of the returned vector equals the number of rows in the matrix.

function is null.
