Merge Two 2D Arrays By Alternating Columns

Solved!
Go to solution

I'm trying to do some simple data manipulation to be used in a csv test report. 

 

Overview:

Input:

Array A =

[ A1 A2 A3 A4]

[ A1 A2 A3 A4]

 

Array B =

[ B1 B2 B3 B4]

[ B1 B2 B3 B4]

 

Desired Output:

[ A1 B1 A2 B2 A3 B3 A4 B4]

[ A1 B1 A2 B2 A3 B3 A4 B4]

 

 

I have two inputs, first is a 2d array of data containing for test data at 7 different points during the test. This data has been converted from double to string.

 

I also have a 2d array of booleans that that initially only has 6 different data points since the first test point does not have a pass/fail critira. Booleans are converted to strings and relabled as "pass" or "fail" and then a blank row is added at the top so that the two array's are the same size.

 

Sample code below

AMAGIS_1-1754669263611.png

 

With the index for "index array" fixed and index fixed for 'insert into array', i can successfully get the first column of Array B inserted into index 1 of array A. however when i try to programmatically connect the index of "index array" (0, 1, 2, 3) and change the insert array index to 1,3,5,7), it doesn't seem to work as i would expect.  

 

Thoughts?

first problem

 

  • Your attached VI does not seem to have any resemblance to the "merge" problem.
  • Your arrays are ambiguous because all rows are the same and we cannot e.g. tell which A1 ends up where.

second problem

 

  • When attaching code, make sure that all controls have reasonable default data. Your code has all empty arrays. Once there is default data, tell us what result you expect (e.g. by manually filling default data into the indicator).
  • Please don't maximize the diagram to the screen!
  • Seems very convoluted, for example the upper two "transpose" cancel each other out, right?

Solution
Accepted by AMAGIS

Making some assumptions, here's a potential "merge" solution (using "interleave 1D arrays")

Did you mean "four" (4) instead of "for"? Does the 2D array have 4 rows and seven columns?

See if this can give you some ideas....

Thanks everyone. The interleave in a for loop is all I needed. Consider this solved.
