Calculator - Special Functions (xmin & xmax)

DineshBabu

Hello,

 I am exploring the special functions in IC 6.1.

I created a simple inverter and used xmin and xmax of the output signal.

When I use xmin and xmax of the output signal with Nth Minimizer value equal to 1, I get the value corresponding to it.

Whereas, when I have the value of Nth Minimizer equal to 2 or more than 2,  I don't get the expected result.

The following is the error message when the value of Nth minimizer is  =>2.

expression evaluation failed: Expression evaluates to nil

expression evaluation failed: xmin(VT("/out") 2 )

 

How do I get around with this issue?

 

Thanks,

Dinesh

    Dinesh,

    Note that xmin and xmax do not return the x-value for a local minimum, but the x-value of the global minimum. The second argument is for when that global minimum (or maximum) appears at more than one x location.

    If you pass 0 as the second argument, you'll get a list of the x values - I suspect there's only one point at which the global minimum/maximum occurs.

    Regards,

    Andrew.
