Question

Matlab short-circuiting behavior into Mathcad

Hi, i need this operator in mathcad (ll)

 

ll  Represents a logical OR operation that employs short-circuiting behavior. That is, expr2 is not evaluated if expr1 is logical 1 (true). Each expression must evaluate to a scalar logical result.

    Look at the Boolean toolbar.  The v symbol does what you want.

    It does the OR, but it doesn't 'short-circuit', does it?

    Mathcads OR does short circuit eval, otherwise doIt(0) would throw an error in the following example

    I have found no reliable way to do that in Mathcad.

    Do you really need it to short-circuit?

    If your first expression is 'per',  then the second expression 'per<0' can also be calculated...

    Mathcad (or at least as I use it) doesn't have functions that return logical true/false.  How about
