    Gaussian Noise Generator

    Hi guys,

    Does anyone know of a C function that will generate gaussian noise?

    Thanks in advance

    Yes.
    Code:
    #include <cmath>
#include <complex>
bool euler_flip(bool value)
{
    return std::pow
    (
        std::complex<float>(std::exp(1.0)), 
        std::complex<float>(0, 1) 
        * std::complex<float>(std::atan(1.0)
        *(1 << (value + 2)))
    ).real() < 0;
}

    Yes, me too
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Generating Gaussian Random Numbers, Taygeta Scientific Inc.

    To change the standard deviation multiply by what you want it to be, and to change the mean add a new mean, I'd imagine.
