Functions
template<class T>
T	scavenge (T scalar, typename linalg_traits< T >::abs_type minabs)
	Returns scalar if its absolute value is not less than minabs, or 0 otherwise.
complex	scavenge (complex scalar, double minabs)
	Overloads scavenge<T> to scavenge the real and imaginary parts of scalar independently.
template<class T>
DenseVector< T > &	internal_tensor (const DenseVector< T > &v1, const DenseVector< T > &v2, DenseVector< T > &result, T scalar, bool overwrite)
	Internal method used to place scalar times the tensor product of v1 and v2 into result.
template<class T>
DenseVector< T > &	internal_tensor (itype N, DenseVector< T > *v_arr[], DenseVector< T > &result, T scalar, bool overwrite)
	Internal method used to place scalar times the tensor product of the first N elements of v_arr into result.
template<class T>
DenseMatrix< T > &	internal_tensor (const DenseMatrix< T > &m1, const DenseMatrix< T > &m2, DenseMatrix< T > &result, T scalar, bool overwrite)
	Internal method used to place scalar times the tensor product of m1 and m2 into result.
template<class T>
DenseMatrix< T > &	internal_tensor (itype N, DenseMatrix< T > *m_arr[], DenseMatrix< T > &result, T scalar, bool overwrite)
	Internal method used to place scalar times the tensor product of the first N elements of v_arr into result.

Function Documentation

complex scavenge (  complex  scalar, double  minabs )  [inline]

Overloads scavenge<T> to scavenge the real and imaginary parts of scalar independently. This is used to eliminate tiny, tiny imaginary (or real) components of numbers that are generated by rounding error.
