Detailed Description

template<class GSG>
class QuantLib::MultiPathGenerator< GSG >

Generates a multipath from a random number generator.

RSG is a sample generator which returns a random sequence. It must have the minimal interface:

RSG {
    Sample<Array> next();
};

Tests:

the generated paths are checked against cached results
