lookup_1d()

template<typename T >

T autoware::common::helper_functions::lookup_1d	(	const std::vector< T > &	domain,
		const std::vector< T > &	range,
		const T	value
	)

Do a 1D table lookup: Does some semi-expensive O(N) error checking first. If query value fall out of the domain, then the value at the corresponding edge of the domain is returned.

Parameters

[in]	domain	The domain, or set of x values
[in]	range	The range, or set of y values
[in]	value	The point in the domain to query, x

Returns

A linearly interpolated value y, corresponding to the query, x

Exceptions

std::domain_error	If domain or range is empty
std::domain_error	If range is not the same size as domain
std::domain_error	If domain is not sorted
std::domain_error	If value is not finite (NAN or INF)

Template Parameters

T	The type of the function, must be interpolatable
