A Vandermonde matrix class.
| NumericT | The underlying scalar type (either float or double) |
| AlignmentV | The internal memory size is given by (size()/AlignmentV + 1) * AlignmentV. AlignmentV must be a power of two. Best values or usually 4, 8 or 16, higher values are usually a waste of memory. |
