Open Live Script

Create a fixed.Interval object. Use the isnan function to determine whether the Interval object is not a number.

interval = fixed.Interval({-pi,pi},{nan,1},{nan,nan});
bool = isnan(interval)
bool = 1x3 logical array

   0   1   1

The output is a logical 1 when the interval contains one or more NaN elements, and 0 otherwise.
