This function returns true if its argument is
monotonic increasing or decreasing, and false
otherwise. If strict=true, then strict monotonicity is
tested, otherwise weak monotonicity is tested.
function isMonotonic extends Modelica.Icons.Function; input Real x[:] "Sequence to be tested"; input Boolean strict = false "Set to true to test for strict monotonicity"; output Boolean monotonic "True if x is monotonic increasing or decreasing"; end isMonotonic;
