IsMissing function

[malsoufi]

Greetings,

Is there a built-in function "IsMissing" in mathcad 14?

if not, what do I have to do?

[ValeryOchkov]

You can try to create the user function!

What should the "IsMissing()" function do?

What parameter(s) does it get, and assuming its result should be Boolean (TRUE or FALSE), when does it result in TRUE?

Program it yourself: IsMissing Function

Unfortunately it is not possible to (user-)define mathcad functions with optional arguments. Neither with mathcad statements, nor via user programmable (.DLL) functions.

So the IsMissing function you are pointing to appears to be useless.
