how can I increment the index of an array in a formula node?

[ernstm]

Hi,

I need some help with the formula node. I need an array, that increment every iteration of the code in the formula node. I need it to save amplitudes.

I thought i could do this with i++; i is the variable for my index.

Hi Martin,

can you please explain a bit more what you need?

Maybe the attached picture can help you.

Hi  Mike,

I need cases with diffrent conditions and in every case  instead of the conditions it should generate a new amplitude for a extern Diode. The Diode send Infrared singnals for testing IR-Receiver.  Some timtes I need the older amplitudes because I must find the smallest singnal on that the receiver can geht enough pulses. So in every case the index must be step up an save in this array element the new amplitude.

I hope I explained well.

Can you put the formula in a for-loop and wire the "I" as input?

I'm not sure what you're after but that'd change the ingoing variable.

Hi Martin,

why do you use the formula node for it?

Hello,

it's true for simple operation why don't you use diag block? 

but may be its a little part of what you make ?

an exemple here:
