Function Documentation

writeFlowObservableToFile()

void IO::writeFlowObservableToFile	(	std::vector< double >	observables,
		std::string	observableName,
		unsigned int	configNumber
	)

IO::writeFlowObservableToFile method for writing a flow observable to file, using .15 precision.

Parameters

observables	a vector of observables.
observableName	observable name.
configNumber	the configuration number.

Top 3 rows of the output file will contain,

• beta,
• NFlows,
• FlowEpsilon, with the rest containing the flowed observable.

writeMatrixToFile()

void IO::writeMatrixToFile	(	std::vector< double >	observables,
		std::string	observableName,
		unsigned int	configNumber,
		unsigned int	N
	)

IO::writeMatrixToFile writes out a matrix of observables to file, i.e. the topological charge in Euclidean time. Uses a .15 precision.

Parameters

observables	the observables in a vector of doubles.
observableName	the name of the observable.
configNumber	the configuration number.
N	the number of columns in the matrix of observables. The number of rows in the matrix is the number of flow steps, NFlows, retrieved from Parameters::getNFlows().

Top 3 rows of the output file will contain,

• beta,
• NFlows,
• FlowEpsilon, with the rest containing the flowed observable.

writeObservablesToFile()

void IO::writeObservablesToFile	(	double	acceptanceRate,
		double	averagedObservable,
		double	varianceObservable,
		double	stdObservable,
		std::vector< double >	observables,
		unsigned int	NObs,
		std::string	observableName
	)

IO::writeObservablesToFile method for writing an observable to file, using .15 precision.

Parameters

acceptanceRate	acceptance rate from the Metropolis algorithm.
averagedObservable	the average of the observable.
varianceObservable	the variance of the observable.
stdObservable	the standard deviation of the observable.
observables	vector of doubles containing the observable.
NObs	the number of configurations, i.e. observables, to be written to file.
observableName	name of the observable. Topological charge, plaquette, energy ect.

The top 8 rows contains,

• beta,
• acceptance rate,
• number of correlation updates used,
• number of configurations,
• number of thermalization steps,
• the average of the observable,
• the variance of the observable,
• the standard deviation of the observable,
