Hi I am using boost/random library in order to create a normal distributed noise. I want to call my my_class::noise() functions several times, but I want to initialize the generator only once. I tried to declare and initialize the generator at the constructor of my_class, but then my_class::noise() doesn't recognized the generator. I wrote it the following way: my_class::my_class() { boost::mt19937 gen(42u); } my_class::noise() { boost::normal_distribution<float> n_d(5, 10); //n_d(mean,stdev) boost::variate_generator<boost::mt19937&, boost::normal_distribution<float>
normal(gen, n_d);
return normal(); } I guess I need to declare the generator at the header, and only initialize it at the constructor, but I don't know how to do it. Thanks for your help. Dvir
