Comparing rows of 2 files

[lecojon]

Oh thank god...and thank you,  on the first view it looks good....

[lecojon]

Hm....

I tried some experiments with your VI to try to get the idea of it.....I´m a beginner, so it´s not very easy for me....

You wrote "ignore the first values under 1" and made a case-structure...if lala = 0...

In my experiment i first delete the first 4 rows and so i can delete the main case-structure,too...(i got more files and the first values aren´t always 0 so i don´t want to always change the number).... but now the prog writes the last row of the 1Hz data at the end of the array although there is no timevalue of 4 Hz data equal to it...

Well, i could delete the last row, too, with "delete from array", but isn´t that a worse way to solve that?

PS: If you or someone else wants, could you please write a short descripton of what the prog does or what happens at each point? It´s so unreproducible for me

Nice day

Hi Lecojon,

well, the programm makes one array out of the two arrays... 

What you ask is acutally not a LabVIEW-specific problem: you just have to find the right algorithm to get the right result - this does not really depend on LabVIEW.

Maybe you should check out the interpolation-functions. Then you wouldnt get four lines which are the same, but maybe that suits you even better. It just depends on what you want. You can find them on the mathematics-palette

Everything in the case structure is just to build the new array. False is there to get the next line and True is there to read the same line several times (till false appears). So in your example 4 times your GPS-Data...

I hope this helps...

Hi,hi, it´s me again.....it didn´t work to start a new thread with this, so i´ll just post that her:

I´m trying to extract a part of an array in an specific interval of time....f.ex.. if time>10 and time < 30 (1st col)---->extract...don´t know so much about this

In the picture it´s red marked.

I think it´s not much, but i´m about to learn....

Hi Lecojon,

I have a example here. I comented it so it should be clear.

Some points: first of all you are writing in the wrong forum!!! Please select LabVIEW if it is a LabVIEW problem and in your case it is.

Secondly please dont post two diffrent kind of questions in the same thread. Maybe some other user has a similar question and will that way never find the solution.

Third point: your questions are very very basic. I would recommend you to search the example finder in LabVIEW and run and understand the examples before posting here. On the web you can also find a lot of webcasts for beginners. It would be good to check them out as well. Next point if you reallly want to get into LabVIEW a training course is the fastest and best way to learn how to programm correctly with LabVIEW.

Thank you very much for your help.

Somehow it did not work to open a new thread...don´t know.

Next time...
