Gilles commented on MATH-989:
-----------------------------

Also, please note that this function is two-dimensional; a single check is not 
enough to ensure a valid call.

We could add a query method like
{noformat}
  public boolean isValidPoint(double x, double y) {
    // ...
  }
{noformat}

Would that be fine for your use-case?

> Exceptions are generally costlier than a test. In the

> is in domain of the interpolator. So, I suggest a function to allow this
