index of retry data

[abdou]

Hi

I have 1D array(A) contain sequence like:
(A) 1 2 7 5 8 6 6 9 74 14
I build an other array (B) contain specific sequence from (A) array:
(B) 2 5 8 9 14
now i would like to build an array (C) contain the indexes from array (A)
I should have :
(C)1 3 4 7 9

so how to build such array?

Thanks

You need to search 1D array A with array B which is indexed in a For loop, and then index the results into array C. See attached example in LV 6.0.

If array (B) has unique value, you can use the search array function to find the index of each of the elements in array (A). See my example below:

If (A) has multiple values that match (B), you can use a nested for loop:

Thanks Kim

but your example doesn't work correctly from index 19 in array (A).
See attached example in LV 6.1

abdou:

This is a pretty easy task.

Straightforward way to do this is:
1) Create a for loop.
2) Pass in array A and array B.
3) Set array B to auto index.
4) Set Array A NOT to autoindex.
5) Then search Array A for the indexed element from array B using
search 1D array. If array A contains the element from array B, search
1D array will return it's index otherwise it returns -1.
6) Wire the return from search 1D array to the right edge of the for
loop and set it to build array. Wire an indicator to the build array
on the right edge of the for loop.
7) If you want to exclude the -1's (not founds) then you will need to
create a different loop to remove them or build the array inside the
for loop using a shift register and a true false selector and a bui
ld
array on the false side and a pass through on the true side.

Please save in version LV6.0 as i dont have LV6.1. Unless someone else wishes to help you instead.
