extract()

template<typename F >

concepts::ElementMatrix< F > hp1D::StiffElementMatrix::extract	(	uint	m,
		uint	n,
		const F	factor
	)		const

Returns the part of the first m rows and n columns multiplied by factor. For simplicity we assume m and n to be at least 2.

Definition at line 57 of file matrices.hh.

getData()

const Array< Real > & concepts::ElementMatrixBase< Real >::getData ( ) const

inlineinherited

Returns the data array

Definition at line 172 of file element.hh.

info()

virtual std::ostream & hp1D::StiffElementMatrix::info ( std::ostream &  os ) const

protectedvirtual

Returns information in an output stream.

Reimplemented from concepts::OutputOperator.

isTranspose()

bool concepts::ElementMatrixBase< Real >::isTranspose ( ) const

inlineinherited

Returns true if the matrix is internally stored as transposed (column-major).

Definition at line 177 of file element.hh.

m()

uint concepts::ElementMatrixBase< Real >::m ( ) const

inlineinherited

Returns the number of rows.

Definition at line 151 of file element.hh.

n()

uint concepts::ElementMatrixBase< Real >::n ( ) const

inlineinherited

Returns the number of columns.

Definition at line 153 of file element.hh.

operator const Real *()

concepts::ElementMatrixBase< Real >::operator const Real * ( ) const

inlineinherited

Returns a pointer to the data array.

Definition at line 169 of file element.hh.

operator()()

const Real & concepts::ElementMatrixBase< Real >::operator() ( const uint  i, const uint  j  ) const

inlineinherited

Returns element (i, j)

Definition at line 156 of file element.hh.

size()

uint concepts::ElementMatrixBase< Real >::size ( ) const

inlineinherited

Returns the number of entries in the matrix.

Definition at line 166 of file element.hh.

storeMatlab()

bool concepts::ElementMatrixBase< Real >::storeMatlab ( const std::string  filename, std::string  name = "", bool  append = false  ) const

inherited

Stores the matrix in a Matlab matrix

Parameters

filename	name of the matlab file, with ending '.m'
name	name of the variable, e.g. "A"
append	if false, create new file, otherwise append to it

Returns

true if the writes was successfull
