Set grid refinement criteria.
ratio | Maximum ratio between grid spacing at adjacent intervals. E.g. (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. |
