Mathematicl basics, How to do an expansion?

[JeanPierre]

JohnnyRocket,

I would create a global VI and put data there as default values of array controls. Just drop a global VI reference when you need it on your diagrams.

Have tried it out and don't seem to be getting any data returned...attached is my humble .vi

Thanks

[JeanPierre]

I have tried your VI with C2H6 and it gives 0.978 for output index 30 and 0.022 for 31. Seems to work here...

[JohnnyRocket]

My hats off to you once again, I didn't understand how to look for the output (ie. 30 & 31)
You truly are a wiz!

Thanks for all your help!!

[JohnnyRocket]

Hehe, one other thing.
I am trying to out put the array to a waveform graph, it works, but I dont want a sloping curve at 30 and 31, I just want a straight line going up and down, one each at 30 and 31. Am trying an XY graph, but am unable to do this?
Any thoughts on this?

Jean-Pierre,

I hate to say it but... you have done it again! Your solution is great! Four stars 4 U!! /Mikael

[JeanPierre]

Thank you Mikael,

Now you know how to put me at work: just challenge me with a statement like "It doesn't appear that Labview is robust enough at mathematical calculations."... 😉

O.K.
My previous answer is stupid.

You can use Mathematics/Numeric Functions/Binomial Coefficients.

Look attached vi.
