Member Function Documentation

rowdim()

size_t rowdim ( ) const

inline

Get the number of rows in the matrix.

Returns

Number of rows in matrix

coldim()

size_t coldim ( ) const

inline

Get the number of columns in the matrix.

Returns

Number of columns in matrix

getStride()

size_t getStride ( ) const

inline

 Get the stride of the matrix.

Returns

stride of submatrix (number of cols of parent matrix)

setEntry()

const Element& setEntry ( size_t  i, size_t  j, const Element &  a_ij  )

inline

Set the entry at (i, j).

Parameters

i	Row index of entry, 0...rowdim() - 1
j	Column index of entry, 0...coldim() - 1
a_ij	Element to set

refEntry()

Element& refEntry ( size_t  i, size_t  j  )

inline

Get a writeable reference to an entry in the matrix.

Parameters

i	Row index of entry, 0...rowdim() - 1
j	Column index of entry, 0...coldim() - 1

Returns

Reference to matrix entry

getEntry() [1/2]

const Element& getEntry ( size_t  i, size_t  j  ) const

inline

Get a read-only individual entry from the matrix.

Parameters

i	Row index of entry, 0...rowdim() - 1
j	Column index of entry, 0...coldim() - 1

Returns

Const reference to matrix entry

getEntry() [2/2]

Element& getEntry ( Element &  x, size_t  i, size_t  j  )

inline

Get an entry and store it in the given value.

This form is more in the Linbox style and is provided for interface compatibility with other parts of the library

Parameters

x	Element in which to store result
i	Row index of entry, 0...rowdim() - 1
j	Column index of entry, 0...coldim() - 1

Returns

Reference to x

getMatrix()

_Matrix& getMatrix ( )

inline

Access the parent matrix.

Returns

Reference to _Mat
