Min. Max function with 2-D array?

[esa_paranoid]

I am trying to take 2 waveforms of data, take the 5 minimum values from one of the waveforms while retaining the corresponding values of the other waveform. Example, if the 10th sample taken of the "sine waveform" is one of the 5 lowest points, I want to save that value as well as the value taken at the exact same time from teh other waveform....

In the actual application I am reading voltage (sine wave) and position using an encoder(square wave). So basically I want to take N samples, take the 5 lowest voltage values obtained, and save each voltage value WITH its position.
So when I look at the front panel and/or a spreadsheet I see something like:
Voltage Reading 1 = -1000 @ 270 degrees

Attached is a generic simulated f
ile I have been trying to get to do this.

Thanks!

Hi Esa

Here is what you want to do implemented.

Did you change your mind for the encoder ?

Hey Doc, no I am still planning on getting an encoder, I am just trying to figure out how to do this so I am simulating 2 signals for now. I thank you for your help, however I am still a bit confused lol.
The file you posted is in 7.1, could you save it and repost it in 7.0 please as I cannot read it.

Thanks!

Sorry for that. Before I thought to check your LVversion, I already had opened your file ...

Anyway, if you have a noisy process, this technique will give very poor results.

Are you really working at ESA ?

No I do not work for ESA, what company is that? If you want to hear where esa_paranoid comes from email me

Ok, thanks for the example Doc, before I saw it I had started working on a way of doing this on my own...I'll post it, tell me if you think your way or this way is a "better" of doing it.

Thanks for all the help!

Hey Doc, check this one out...this is probably more along what I was thinking...how does it look?

European Space Agency!
