pub fn sample_paths<P: StochasticProcess>(
process: &P,
x0: &[f64],
cfg: &SampleConfig,
) -> MultiPathsExpand description
Simulate paths of an N-state process from the state x0. The
stepping scheme is the process’s own evolve
(multi-factor schemes are process-owned — e.g. Heston full-truncation
or QE); dw carries independent increments, any factor correlation
lives inside the process.
