Function Documentation

◆ cube_root()

template<typename Scalar >

Scalar ecl::cube_root ( const Scalar & x )

inline

The real solution to a cube root.

Parameters

x	: scalar to test.

Template Parameters

Scalar : a real numerical value

Returns: Scalar : real value solution to the cubic root

Definition at line 97 of file simple.hpp.

◆ euclidean_norm() [1/2]

template<typename T >

T ecl::euclidean_norm	(	const T &	x1,
		const T &	x2
	)

Function for euclidean norms of dimension 2.

Parameters

x1	: first argument
x2	: second argument

Returns: T : result of the input.

Definition at line 82 of file norms.hpp.

◆ euclidean_norm() [2/2]

template<typename T >

T ecl::euclidean_norm	(	const T &	x1,
		const T &	x2,
		const T &	x3
	)

Function for euclidean norms of dimension 3.

Parameters

x1	: first argument
x2	: second argument
x3	: second argument

Returns: T : result of the input.

Definition at line 95 of file norms.hpp.

◆ isApprox()

template<typename Scalar , typename OtherScalar >

bool ecl::isApprox	(	const Scalar &	x,
		const OtherScalar &	y,
		typename numeric_limits< Scalar >::Precision	precision = `numeric_limits<Scalar>::dummy_precision`
	)

inline

Checks if two values are approximate.

Note that this does not use the usual direct epsilon bound check, instead, it uses the magnitudes of the values and supplied precision to determine the epsilon bounds before carrying out the operation.

Parameters

x	- first input argument
y	- second input argument
precision	- precision to use (default is defined by the type).

Returns: bool : true or false of the operation.

Definition at line 154 of file fuzzy.hpp.

◆ isApproxOrLessThan()

template<typename Scalar , typename OtherScalar >

bool ecl::isApproxOrLessThan	(	const Scalar &	x,
		const OtherScalar &	y,
		typename numeric_limits< Scalar >::Precision	precision = `numeric_limits<Scalar>::dummy_precision`
	)

inline

Checks if the first value is less than or approximate to the second.

Note that this does not use the usual direct epsilon bound check, instead, it uses the magnitudes of the values and supplied precision to determine the epsilon bounds before carrying out the operation.

Parameters

x	- first input argument
y	- second input argument
precision	- precision to use (default is defined by the type).

Returns: bool : true or false of the operation.

Definition at line 172 of file fuzzy.hpp.

◆ nsign()

template<typename Scalar >

int ecl::nsign ( const Scalar & x )

inline

A sign function for numerical values (negative return if arg is zero).

Note that zero will return -1, positive numbers +1, and negative numbers -1.

Parameters

x	: scalar to test.

Template Parameters

Scalar : some numerical quantity satisfying a comparison with >= 0

Returns: bool : true if x is >= 0.

Definition at line 80 of file simple.hpp.

◆ psign()

template<typename Scalar >

int ecl::psign ( const Scalar & x )

inline

A sign function for numerical values (positive return if arg is zero).

Note that zero will return +1, positive numbers +1, and negative numbers -1.

Parameters

x	: scalar to test.

Template Parameters

Scalar : some numerical quantity satisfying a comparison with >= 0

Returns: bool : true if x is >= 0.

Definition at line 61 of file simple.hpp.

◆ sign()

template<typename Scalar >

int ecl::sign ( const Scalar & x )

inline

A sign function for numerical values.

Note that zero will return zero, positive numbers +1, and negative numbers -1.

Parameters

x	: scalar to test.

Template Parameters

Scalar : some numerical quantity satisfying a comparison with >= 0

Returns: bool : true if x is >= 0.

Definition at line 38 of file simple.hpp.
