double randvar_normal_density_approx

(double x, double mean,
  double u)

Determinates the value of the one dimensional density function phi( mean, u ) for the normal distribution at point x.

Documentation

Determinates the value of the one dimensional density function phi( mean, u ) for the normal distribution at point x. The value is got from a previoously calculated list, which is made in first call to this function.

Parameters:

x - : point value
mean - : mean value for the normal distribution
u - : variance for the normal distribution ($\sigma^2$)

Returns:

function value
