How can I write a sum formula in LabView? Help!!

[AnnihilationSpectrum]

I need to implement this formula in Labview.

but not on the formula node.

Could you help me please?

You need array index and for loop

Hi Anni,

for those sums in nominator and denominator you need an ArraySubset followed by SumArray function. No loops needed!

Thank you for your reply, but how? The formula is pretty easy, but for Labview it's hard for me. Could you show me? For example how can i write sum with index array in for loop

Hi Anni,

did you ever tried to use Quickdrop? Ctrl-Space?

See this:

Please check the calculation, especially the inputs of those ArraySubset functions.

Gerd, you need ("end"-"start"+1) for length.

Hi Artem,

that's why I asked Anni to check the ArraySubsets… 😄
