Function nalgebra_numpy::matrix_slice_from_python_ptr

pub unsafe fn matrix_slice_from_python_ptr<'a, N, R, C>(
    array: *mut PyObject
) -> Result<MatrixSlice<'a, N, R, C, Dynamic, Dynamic>, Error> where
    N: Scalar + TypeNum,
    R: Dim,
    C: Dim, 

Same as matrix_slice_from_python, but takes a raw PyObject pointer.
