Mathscript Interactive Window Exists... but not Mathscript Node

[mschmit]

I have come across a task where I'd like to utilize LabView Mathscript.  However, I do not seem to have the Mathscript node on my block diagram function palette.

Mathscript does exist in the Tools > Mathscript Window drop down menu.

I am running LabView 8.2 Professional Development Edition with Real-Time module.  I will be deploying the VI with Mathscript node to a PXI platform with RTOS.  Mathscript should be compatible, right?

Any tips on how to get the Mathscript node on my block diagram?  Did I good when installing LabView somewhere?

Thanks!

Hello,

At this time, LabVIEW MathScript can only be targeted to the desktop PC.  However, LabVIEW RT is on our roadmap.  It sounds like you are working under an RT target.  Consequently, the palettes will only show the structures and functions available to RT.  If this is not the case, let me know.  In general, if the MathScript Window menu option is available, then the node should be, too.

Grant,

Thanks for the response.  I figured out AFTER I posted the message that Mathscript wasn't supported on RT platforms.  I guess I'll have to suck it up and try to program the algorithm in LV blocks or create a DLL from my Matlab code or C code to do what I want.

BTW, the Mathscript node is available when I select the desktop target "My Computer" as opposed to the PXI chassis.  Thanks for th feedback and keep up the good work.  I look forward to seeing Mathscript for RT targets soon.

Well it has been another two years.  And still no MathScript for LV RT.

This is typical.  NI will make the promise of support in the near future and then never follow through.

Kmcdevitt,

Without saying too much, perhaps you should check back in August.

Howdy McJeff,

Well its still July, not even August yet, and there is a bunch of stuff appearing all over the ni.com website about MathScript RT and LabVIEW 2009 and other goodies.

Tell me McJeff, is there to be a Printed Manual or a PDF on MathScript RT?

Is it posable to programatically generate the "script" dynamically for a MathScript Node?  It would be assumed that the Node Inputs and Outputs would be the same, just the math applied would change during execution.

We could use code, LabVIEW, or MathScript, to generate "script" for another MathScript.  We could call it McScript!

Hello,

To my knowledge, we have not yet created a manual specifically for using MathScript on RT.  Certain functions are not available on RT or are available with caveats.  You can find a list of such functions below:

As for programmatically generating the script dynamically for the MathScript node, see the following thread for more information:
