How to generate random numbers from a normal disribution

[qingze]

I found a function but not sure whether it works.

double randgauss(double min, double max, double sigma, double centre)
{
	double random = (min + (max-min) * (double)rand()/RAND_MAX); //create random domain between [min,max]
	double tmp = (random-centre)/sigma; 
	double gauss= exp(-tmp*tmp/2); //gaussian formula
	return (gauss);
}

In matlab this can be done in one sentence but in C++ it becomes much more difficult.

It can be done in one sentence in C++ as well, except in C++ it is called "normal distribution", or, more exactly, std::normal_distribution

see for example

Got it! Thanks so much for your help!
