Detailed Description

template<class Blackbox1, class Blackbox2>
class LinBox::DirectSum< Blackbox1, Blackbox2 >

If C = DirectSum(A, B) and y = xA and z = wB, then (y,z) = (x,w)C.

And similarly for apply.

Constructor & Destructor Documentation

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. Parameters: 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). Parameters: A_ptr  pointer to black box matrix A. B_ptr  pointer to black box matrix B.

DirectSum (  const DirectSum< Blackbox1, Blackbox2 > &    M )  [inline]

Copy constructor.

~DirectSum (  void    )  [inline]

Destructor.
