Flipping the array

[rpr]

Can you guys tell me how to flip a 2d array?  So if i have a 100x100 array i want the 100x100th element to be placed at 1,100.Help please!!!!!!!!!!!!!!!!!!!!!

You will need to better define "flip a 2D array" since there is no definition for that. Are you "flipping" along a diagonal? Or are you just flipping those two positions?

I'm sorry, but 100x100th element makes no sense.  Since a 100x100 array  has 10000 elements, how does placing the next element at position 1100 make any sense?

Place a for loop and a Reverse 1D Array inside it. Wire the 2D array into the for loop and back out through the function and you will get a 2D array back. The auto-indexing will make the code work on each row of the array. If you want to work on the columns, you can use the Transpose 2D Array function.

Is this what you had in mind, by chance?

It's certainly what I had in mind.

By the way, Cory, you might find the Code Capture Tool useful.

Great minds must think alike! And indeed, that does look like a very useful tool...thanks for pointing it out to me 😄

After seeing dozens of references and reccomendations for the CCT, I finally downloaded it.  Kudos and a hearty thank you to both Yair and Ton! I have MWSnap, and could not imagine how the CCT could make things any easier than that.  I was WRONG.

We tried hard to make it extremely easy to install and to use on as many platforms and versions as possible. 

Well, on the GUI side, anyway. Only after we released I tried writing some new capturing code using the API and found out that it kind of sucked, because its error reporting wasn't very good and I assumed all kinds of stuff which was wrong when "designing" the API.

But, all's well that ends well. I believe the current version on LAVA should have all the nice error reporting and flow required to use it.
