Detailed Description

numbers with a user defined probaility density function.

Call setup() or use the constructor to provide a function-expression with one variable (e.g. 'x^2'). Call get() to retrieve a random number that follows the given probabilty density function. The provided function is not bound to a specific value range, but should produce values below 40.

get()

double RandomCustomPDF::get

(

)

get a random number

getProbOfRange()

double RandomCustomPDF::getProbOfRange	(	const double	lowerBound,
		const double	upperBound
	)

get probability of random numbers between given bounds.

setup()

void RandomCustomPDF::setup	(	const QString &	funcExpr,
		const double	lowerBound = 0.,
		const double	upperBound = 1.,
		const bool	isSumFunc = false,
		const int	stepCount = 100
	)

setup of the properites of the RandomCustomPDF.

funcExpr the probability density function is given as a string for an Expression. The variable (e.g. 'x') lowerBound lowest possible value of the random numbers (default=0) upperBound highest possible value of the random numbers (default=1) isSumFunc if true, the function given in 'funcExpr' is a cumulative probabilty density function (default=false) stepCount internal degree of 'slots' - the more slots, the more accurate (default=100)
