IsFiniteOp ( const SparseStencilMatrix & m )

inline

Member Function Documentation

eq()

bool eq ( const SparseStencilMatrix< OtherValueType, STENCIL_SIZE > & other, ValueType eps = Tolerance<ValueType>::value() ) const

inline

Return true if this matrix is equivalent to the given matrix to within the specified tolerance.

getConstRow()

SparseStencilMatrix< ValueType, STENCIL_SIZE >::ConstRow getConstRow ( SizeType row ) const

inline

Return a read-only view onto the given row of this matrix.

getRowEditor()

SparseStencilMatrix< ValueType, STENCIL_SIZE >::RowEditor getRowEditor ( SizeType row )

inline

Return a read/write view onto the given row of this matrix.

getValue()

const ValueType & getValue ( SizeType row, SizeType col ) const

inline

Return the value at the given coordinates.

Warning

It is not safe to get values from a row while another thread is setting values in that row.

isFinite()

bool isFinite ( ) const

inline

Return true if every element of this matrix has a finite value.

numRows()

SizeType numRows ( ) const

inline

Return the number of rows in this matrix.

operator()() [1/2]

template<typename ValueType_, SizeType STENCIL_SIZE>

bool operator() ( const SizeRange & range, bool finite ) const

inline

operator()() [2/2]

const ValueType & operator() ( SizeType row, SizeType col ) const

inline

operator*=()

SparseStencilMatrix & operator*= ( const Scalar & s )

inline

scale()

void scale ( const Scalar & s )

inline

Multiply all elements in the matrix by s;.

setValue()

void setValue ( SizeType row, SizeType col, const ValueType & val )

inline

Set the value at the given coordinates.

Warning

It is not safe to set values in the same row simultaneously from multiple threads.

size()

SizeType size ( ) const

inline

SparseStencilMatrix() [1/2]

SparseStencilMatrix ( const SparseStencilMatrix & other )

inline

Deep copy the given matrix.

SparseStencilMatrix() [2/2]

SparseStencilMatrix ( SizeType n )

inline

str()

std::string str ( ) const

inline

Return a string representation of this matrix.

vectorMultiply() [1/2]

void vectorMultiply ( const Vector< VecValueType > & inVec, Vector< VecValueType > & resultVec ) const

inline

Multiply this matrix by inVec and return the result in resultVec.

Exceptions

ArithmeticError

if either inVec or resultVec is not of size N, where N x N is the size of this matrix.

vectorMultiply() [2/2]

void vectorMultiply ( const VecValueType * inVec, VecValueType * resultVec ) const

inline

Multiply this matrix by the vector represented by the array inVec and return the result in resultVec.

Warning

Both inVec and resultVec must have at least N elements, where N x N is the size of this matrix.
