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. |
