Formula Node Troubles

[a1wd3]

I'm a beginner with LabVIEW and I am working with the formula node.  My program is not running.  The error I am recieving is "array indexing expected".  What exactly does that mean?  All my input arrays are defined outside of the node.

Don't be shy.  Post your code so we can see what you are doing.  This is a place of learning.  🙂

I also can't seem to get array outputs and a place to wire my error output.

You need to index your arrays in the formulas.  Are you trying to get arrays going out?  Scalers and arrays do not mix inside of the formula node.  You could probably do all of that in actualy LabVIEW code instead of using the Formula Node.

Yeah, I'm trying to get arrays in my outputs.

Hi a1,

- the formula node doesn't handle arrays...

- it doesn't handle error clusters...

- the help for the node also doesn't mention a function "ones(x,y)"...

Well that's annoying.  I guess I'll just try doing it without the formula node.  Any ideas on how to make it any easier? Thanks.

Hi a1,

an idea would be to use MathScript instead - when your LabVIEW license permits...

[a1wd3]

Ok, how to I access Math Script?

Hi a1,

when you have it installed (and your license is valid) you will find it next to the formula node in the structures palette...
