extracting multiple arrays from a 1D array

[s.steen]

Hi,

I tried both codes (again thank you all).
I couldn't load the snippet because I'm using an earlier version..
@ crossrulez: I don't get only the "squared signal" values out of your code, but I get the whole signal divided into subarrays and each array contains one of the square signals. There's no problem to again extract the only square signal in each array.. now it's easier. But may be I missed something in the code (?)
@ jwscs: What do you mean by fixed corner cases? I tried your code, and I couldn't get what i want .. don't know exactly what I did wrong. Did you get out the correct array values?

[crossrulz]

In your attempt of doing my code, your FOR loop is wrong.  You used Replace Array Subset when you should have use Array Subset.  What the icons carefully.

..Oh yes..sure!! now it works of course! Thank you very much crossrulz!

you missed the "Transpose 2D Array" after reading from spreadsheat

EDIT: 'fixed corner cases' was added by me, because i edited my post and replaced the first snippet with a newer one

Great. Thanks!!

LabVIEW does not support "ragged" 2D arrays, so all rows will be padded to the longest row. You can do a 1D array of clusters, each containing a 1D array to have each "row" a different length.

What exactly is so interesting in this data that you need to keep it all? What are you planning to do with the result? Wouldn't it be sufficient to just keep e.g. the time of the OFF-ON transition and the length of the ON time for each?

yes.. thanks for the tip!

It's the data coming out of one channel during an ultrasonic measuring procedure. The length of the echoes should be measured (of each of those 1D arrays) and serve as a reference for other simulated values. I don't know how to detect the On to Off transition time.. isn't it the same idea as what is in the solution code?
would be great if u reply!

Detecting on-off transitions is very similar to detecting off-on transitions.
