Replace Array Subset-trouble!

[OscarJ]

Yo people, I have encountered a super-annoying problem, and the limited LabVIEW knowledge my brain holds at this moment seems insufficient for a satisfactory solution of this problem. I therefore need assistance in the form of additional LabVIEW-skill, which is what I hope to achive by post my question here!!!

I would like to: 1. let a forloop create three arrays

                       2. Replace portions of three columns in another 2D array with these three arrays.

Perhaps there is an easier approach than the one I've used?

This did work when I tried to do it with an array of strings:

but whats wrong when I try with DBL-arrays?

The original string-array has eight columns, but I only want to replace columns 5, 6 and 7, and the number of rows to replace=number of rows in new array,replace happens from the row specified by the wire that goes into the "index(row)". All this works fine, but in the DBL-example there is only three columns in both the new array, and the one I wish to replace elements in, but the wire appears broken  what is it that I've missed here?

Hi

In your first example you have both the row and column indices wired to the replace array subset function, in your second you only have the row wired. In this case the replace array subset is expecting a 1D array but is getting a 2D array, hence the broken wire.

To fix it wire a constant to the column index. Since you are replacing all 3 columns try wiring a 0 to it.

If you look carefully at your 2-D string string example, you'll notice that you have wires two indexes to the Replace Array Subset.

If you wire the bottom index (column) to your 2-D numeric array, it should be okay.

You guys did it! Thank you very much for taking time and solving my super-annoying problem!

Turns out I won't ever be an awesome LabVIEW-programmer since I keep messing up, and wasting time like this all the time though

Don't be hard on yourself.

We all had to start and learn..    You'll do great!  Keep visiting this forum, as it is a fantastic place to learn.

I still learn..  it never ends.. 😉 😄

Multi-dimentional array manipulation was one of the harder concept to get my head around. I remeber asking the local NI rep (when I was just a "G-babe") about a similar problem. He rolled his eyes and just walked away.
