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.

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
