Detailed Description

template<class Blackbox>
class LinBox::Squarize< Blackbox >

transpose matrix without copying.

Parameters

Vector

LinBox dense or sparse vector of field elements

Constructor & Destructor Documentation

Squarize() [1/2]

Squarize ( const Blackbox &  A )

inline

Constructor from a black box.

This constructor creates a matrix that the transpose of a black box matrix A

Parameters

A	pointer to black box matrix.

Squarize() [2/2]

Squarize ( const Squarize< Blackbox > &  M )

inline

Copy constructor.

Creates new black box objects in dynamic memory.

Parameters

M	constant reference to compose black box matrix

Member Function Documentation

apply()

Vector1& apply ( Vector1 &  y, const Vector2 &  x  ) const

inline

Application of BlackBox matrix.

y= A*x. Requires one vector conforming to the LinBox vector archetype. Required by abstract base class.

Returns

reference to vector y containing output.

Parameters

x	constant reference to vector to contain input
y

Todo:

use field().zero

applyTranspose()

Vector1& applyTranspose ( Vector1 &  y, const Vector2 &  x  ) const

inline

Application of BlackBox matrix transpose.

y= transpose(A)*x. Requires one vector conforming to the LinBox vector archetype. Required by abstract base class.

Returns

reference to vector y containing output.

Parameters

x	constant reference to vector to contain input
y

Todo:

use field().zero

rowdim()

size_t rowdim ( void  ) const

inline

Retreive row dimensions of BlackBox matrix.

This may be needed for applying preconditioners. Required by abstract base class.

Returns

integer number of rows of black box matrix.

coldim()

size_t coldim ( void  ) const

inline

Retreive column dimensions of BlackBox matrix.

Required by abstract base class.

Returns

integer number of columns of black box matrix.
