#include <archetype.h>
This simple interface is all that is needed for the blackbox algorithms. Alternatively, the matrix archetype provides individual matrix entry access, as needed by some algorithms, such as elimination methods.

y := Ax, matrix-vector product. The vector x must be of size A.coldim(), where A is this blackbox. On entry to apply, the vector y must be of size A.rowdim(). Neither vector has it's size or capacity modified by apply. Apply is not responsible for the validity of the sizes, which may or may not be checked. The two vectors may not overlap in memory.

y := Ax, matrix-vector product using a handle for ... The handle serves as "protection from the future". The idea is that the handle could allow the blackbox to operate more as a pure container, with the field (or other functionality such as dot product) provided through the handle. However, there are no known current uses (2003 june). |

y := xA, vector-matrix product. (Or from a column vector viewpoint: y := AT x, matrix transpose times vector product. ) The vector x must be of size A.rowdim(), where A is this blackbox. On entry to apply, the vector y must be of size A.coldim(). Neither vector has it's size or capacity modified by applyTranspose. ApplyTranspose is not responsible for the validity of the sizes, which may or may not be checked. The two vectors may not overlap in memory.
