Defines a continuous random variable.

Constructor & Destructor Documentation

ContinuousVariable() [1/4]

template<typename GUM_SCALAR = float>

gum::ContinuousVariable< GUM_SCALAR >::ContinuousVariable	(	const std::string &	aName,
		const std::string &	aDesc,
		GUM_SCALAR	lower_bound = -std::numeric_limits< GUM_SCALAR >::infinity(),
		GUM_SCALAR	upper_bound = std::numeric_limits< GUM_SCALAR >::infinity() )

Default constructor.

It is possible to create ContinuousVariable with lower_bound > upper_bound. In this case, the min and the max are swapped. By default, the range of the variable is (-inf,+inf).
