Constructor & Destructor Documentation

libfbm::PowerLawContext::PowerLawContext	(	double	H,
		const zvec &	dim,
		double	Var = 2.0
	)

Constructor.

Var determines the variance or cov(0). This parameter strongly affects whether circular matrix embedding works or not. You can decrease this to 1 when . Note that as H approaches 0 the field becomes distorted. H=0.01 should still be quite fine.
