compare_with_tol()

BEM_INLINE bool bem::compare_with_tol	(	const Complex	val,
		const Complex	val_ref,
		const Float	tol = 1e-3,
		const uint8_t	mode = 1
	)

Compares two complex numbers within a given tolerance based on a given rule.

Parameters

[in]	val	- Value to check.
[in]	val_ref	- Reference value.
[in]	tol	- Tolerance (optional).
[in]	mode	- Comparison mode: 1: Compare real and imaginary parts separately (default). 2: Compare magnitude and phase separately. 3: Compare the absolute value.

Returns

true if the two values are within the specified tolerance, false otherwise.

load_rules()

template<uint8_t dim>

std::vector< QuadratureRule< dim > > bem::load_rules	(	const std::string	file,
		ConstEigRef< EigColVec< Index > >	orders
	)

Loads quadrature rules from the specified json file assumed to be located in the same directory as this file.

Template Parameters

dim	- Dimension in which the quadrature rules are defined.

Parameters

[in]	file	- json file name.
[in]	orders	- List of orders to load.

Returns

Vector of quadrature rule objects.
