Information
Syntax
Normal.density(u, u_min=0, u_max=1, mu=0, sigma=1);
Description
This function computes the probability density function according to a truncated normal distribution with minimum value u_min, maximum value u_max, mean value of original distribution mu and standard deviation of original distribution sigma (variance = sigma2). Plot of the function:
