| - | * Unfortunately SysML or Sparx EA doesn't have any mathematical functions, like 'min()' to return minimum value of a set, out of the box. That's where you come in. | + | * Modelica supports a limited number of mathematical functions, like 'min()' to return minimum value of a set, out of the box. If you want to create a function, say range() then that's where you come in. Note the below created function is obsolete as min() already exists (at the time of writing this function I didn't know that...) |
