function setRefineCriteria(s, n, ratio, slope, curve, prune)
% SETREFINECRITERIA  Set the criteria used to refine the grid.
% s = setRefineCriteria(s, n, ratio, slope, curve, prune)
% :param s:
%     Instance of class :mat:func:`Stack`
% :param n:
%     Domain number
% :param ratio:
%     Maximum size ratio between adjacent cells
% :param slope:
%     Maximum relative difference in value between
%     adjacent points
% :param curve:
%     Maximum relative difference in slope between
%     adjacent cells
% :param prune:
%     Minimum value for slope or curve for which points
%     will be retained in the grid. If the computed
%     slope or curve value is below prune for all
%     components, it will be deleted, unless either
%     neighboring point is already marked for deletion.
