And similarly for apply.
DirectSum | ( | const Blackbox1 & | A, |
const Blackbox2 & | B | ||
) | [inline] |
Constructor from two black box matrices. This becomes direct sum of A and B. They may be rectangular.
A,B,: | black box matrices over a common field. |
DirectSum | ( | const Blackbox1 * | Ap, |
const Blackbox2 * | Bp | ||
) | [inline] |
Constructor from two black box matrix pointers. This becomes direct sum of A and B. They may be rectangular. They must be over the same field (or ring).
A_ptr | pointer to black box matrix A. |
B_ptr | pointer to black box matrix B. |
