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() [1/3]

template<class _Blackbox1, class _Blackbox2>

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	black box matrices over a common field.
B	black box matrices over a common field.

DirectSum() [2/3]

template<class _Blackbox1, class _Blackbox2>

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

Ap	pointer to black box matrix A.
Bp	pointer to black box matrix B.

DirectSum() [3/3]

template<class _Blackbox1, class _Blackbox2>

DirectSum ( const DirectSum< Blackbox1, Blackbox2 > & M )

inline

Copy constructor.

~DirectSum()

template<class _Blackbox1, class _Blackbox2>

~DirectSum ( void )

inline

Destructor.
