Detailed Description

template<class T>
class QUESO::StdScalarCdf< T >

A class for handling standard CDFs.

This class implements a standard cumulative distribution function (CDF). Its protected attribute m_sampledCdfGrid is an object of the class SampledScalarCdf<T>, so all members of this class are implemented using the members of SampledScalarCdf<T>.

Constructor & Destructor Documentation

template<class T >

QUESO::StdScalarCdf< T >::StdScalarCdf	(	const BaseEnvironment &	env,
		const char *	prefix,
		const std::vector< T > &	cdfGrid,
		const std::vector< double > &	cdfValues
	)

Default constructor.

Instantiates an object of the class given a prefix, the environment, the grid points where it will be evaluated and its resulting values.
