Detailed Description

template<FloatingPointType F>
struct MC::Distributions::Normal< F >

Represents a normal (Gaussian) probability distribution.

The normal distribution is parameterized by a mean and a standard deviation. It supports random sampling, computing statistical properties.

Template Parameters

F	Floating-point type (must satisfy FloatingPointType).
