Function Documentation

void CheckDistribution

(

)

Check the frequency distribution and report interesting things to console.

int main	(	int	argc,
		char *	argv[]
	)

Prompts the user for a random number seed and a tail multiplier, then measures statistics, and saves information about the distribution to a file.

Parameters

argc	Argument count
argv	Arguments.

Returns

0 for success, 1 for failure.

void ResetDistribution

(

)

Reset all the statistics to zero. Call this before you start measuring.

void RunExperiment	(	float	omega,
		int	n
	)

Run an experiment to measure the frequency distribution.

Parameters

omega	The tail multiplier, which controls how low the tails of the distribution can be.
n	Number of times to repeat the experiment.

void SaveDistribution

(

FILE *

filehandle

)

Save the frequency distribution.

Parameters

filehandle

File handle opened for writing.
