Formula waveform.vi - functions list?

[dukevn]

I am trying to feed formula waveform.vi with some functions, and I try to search, or read help etc to see whether there is a list of functions that can be typed in the formula field (and hence can be understood by the vi), but with no luck. So far, I try sin, cos, multiple (*), abs - which are fine, but heaviside or delta, or even logical function such as (t>0.2), they all do not work. Anybody knows about such a list? Can I use delta dirac or heaviside function there?

Thanks.

dukevn,

There are links to built in expressions, operators, etc. for formulas nodes here:  https://www.ni.com/docs/en-US/bundle/labview-api-ref/page/functions/formula-node.html

Please be aware that debug is limited in the formula node so you may want to break more difficult functions into smaller peaces or write them in standard LabVIEW.

Regards,

SS

Hi,

Even I already figured how to produce step function with abs (and then heaviside and such), but this list is still completely useful to me. Thanks a bunch 🙂
