2d array iteration

[quexin]

How to iterate through a 2d array in such a manner, if the array contents is:

Header1  Header2  Header1  Header2   Header1   Header2.......(repeat sequence)

4               False         2               True......................(repeat sequence)

7               False         3               True.....................(repeat sequence)

3               True           2               false ...................(repeate sequence)

5               False         6               false....................(repeat sequence)

But, it should iterate:header 1 row 1, then header 2 row 1, then header 1 row 2, then header 2 row 2......

Once it finishes iterating through columns 1 and 2, it should move on to column 3 and 4 and do the same process.

What version of LabVIEW are you using?  If you have the concatinating tunnels (new in LabVIEW 2013?), then this is simple.

That is Great!! and I have labVIEW 2014 so this works out.

Thank you!

Also, just curious not related to my original post (Well, it might be), how do most people really understand and learn to operate labVIEW at a high level?

One way is to find a LabVIEW Guru and apprentice yourself to him/her.  You want to see "good code" and have an explanation of "what makes this good".  There are some General Principles that seem to characterize good code -- one is that almost every VI fits on a single screen (which means that there are probably a lot of sub-VIs).  Early in my experience with LabVIEW I read "The LabVIEW Style Book", and learned a lot from it.

So, another question....

How do I make it so it stores (Using crossrulz array content) ab, cd, ef in the first two columns.

Then it stores gh, ij, kl in the next two columns, and repeat.....

Please re-phrase your question it isn't clear what you are asking.  You say put "ab, cd, ef" in the first two columns, but you just listed three things if the commas is the delimeter between items.  How would you want to store three things in two columns?  Please post clearly what you want your output to be, and post any code you have tried if you have any.

so the array will look like this in the end:

Column1     Column2     Column3     Column4     Column5       Column6..............

a                   b                    g                   h                    m                     n

c                   d                    i                     j                     o                      p

e                   f                     k                    l                     q                      r

I have attached some code....it is really messy because I am trying to understand what is going on in for loops and coming out of array operations, therefore, I created some indicators. I did not add much after using Crossulz code.

Uh....isn't that the input?  Are you asking how to reverse crossrulz code?

[akovaski]

If what you want is to revert the operation, you can use the same (basically) operation that crossrulz gave, but looking transpositionly.

.........whoops my bad....I have no idea what I am trying to accomplish....Sorry for wasting time on that post
