Functions
template<typename Number >
Number	numeric::clamp (Number value, Number lower_bound, Number upper_bound)
	Clamps to the closed interval [lower_bound, upper_bound]. Templated type must implement operator<. More...
double	numeric::log (double x, double base)
	Computes log(x) in the given base. More...
bool	numeric::equal_by_epsilon (numeric::Real value1, numeric::Real value2, numeric::Real epsilon)
	are two Real values are equal up to some epsilon More...
numeric::Real	numeric::median (utility::vector1< numeric::Real > const &values)
	Returns the median from a vector1 of Real values. More...
numeric::Real	numeric::mean (utility::vector1< numeric::Real > const &values)
template<typename T >
T	numeric::max (utility::vector1< T > const &values)
template<typename T >
T	numeric::min (utility::vector1< T > const &values)
Real	numeric::boltzmann_accept_probability (Real const score_before, Real const score_after, Real const temperature)
	Calculates the acceptance probability of a given score-change at the given temperature, generally used in simulated annealing algorithms. Returns a value in the range (0-1). More...
template<typename T >
T	numeric::find_nearest_value (typename utility::vector1< T > const &input_list, T key, platform::Size min_index, platform::Size max_index)
	recursive binary search that finds the value closest to key. Call find_nearest_value(input_list,value) instead. It's the driver function for this function. This fails miserably (and silently!) on a non-sorted vector, so don't do that!. More...
template<typename T >
T	numeric::find_nearest_value (typename utility::vector1< T > const &input_list, T key)
	given a vector and an input value, return the value in the vector that is closest to the input This is a wrapper for find_nearest_value(input_list,key,min,max) and insures that you're sorted. More...
Real &	numeric::access_Real_MathNTensor (MathNTensorBaseOP< Real > tensorbase, utility::vector1< Size > const &position)
	Utility function to access an entry in a MathNTensor of arbitrary dimensionality unknown at compile time, given a MathNTensorBaseOP. More...
Real const &	numeric::const_access_Real_MathNTensor (MathNTensorBaseCOP< Real > tensorbase, utility::vector1< Size > const &position)
	Utility function to access an entry in a MathNTensor of arbitrary dimensionality unknown at compile time, given a MathNTensorBaseCOP. More...
Size	numeric::get_Real_MathNTensor_dimension_size (MathNTensorBaseCOP< Real > tensorbase, Size const dimension_index)
	Given a MathNTensorBaseCOP, get the size along one dimension. More...
