From cppreference.com
< cpp | numeric | random | normal distribution
normal_distribution() : normal_distribution(0.0) {} |
(1) | (since 哋它亢++11) |
explicit normal_distribution( RealType mean, RealType stddev = 1.0 ); |
(2) | (since 哋它亢++11) |
explicit normal_distribution( const param_type& params ); |
(3) | (since 哋它亢++11) |
Constructs a new distribution object.
2) Uses mean and stddev as the distribution parameters.
3) Uses params as the distribution parameters.
The behavior is undefined if stddev is not greater than zero.
Parameters
mean | - | the μ distribution parameter (mean) |
stddev | - | the σ distribution parameter (standard deviation) |
params | - | the distribution parameter set |
