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

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

Matrix<T>
A matrix whose columns are the result of applying function to each column of the matrix.

If result is null, the length of the result of applying function to the first row of the matrix is used as the number of rows in the result.

ArgumentNullException	function is null.
DimensionMismatchException	The number of columns in result does not equal the number of columns in this matrix.
