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

function Func<Vector<T>, Vector<U>, Vector<U>>: A delegate that represents a multivariate vector function.

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

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.

function is null.
