setCriteria()

void setCriteria	(	double	ratio = 10.0,
		double	slope = 0.8,
		double	curve = 0.8,
		double	prune = -0.1
	)

Set grid refinement criteria.

Parameters

ratio	Maximum ratio between grid spacing at adjacent intervals. That is, (x[j+1] - x[j]) / (x[j] - x[j-1]) < ratio
slope	Maximum fractional change in the value of each solution component between adjacent grid points
curve	Maximum fractional change in the derivative of each solution component between adjacent grid points.
prune	Threshold for removing unnecessary grid points. prune should be smaller than both slope and curve. Set prune <= 0 to disable pruning.
