Combining two 1d arrays into a single 1d array?

[chazzchuzz]

I have two 1d arrays that look like so:

There is always a zero in one of the arrays, but never both.  Is there any way I can combine just the nonzero values into a single 1d array?  Thanks for the help.

Concatenate the arrays.  Then repetitively search the new 1-D array for zero values and delete them from the array.

[chazzchuzz]

I tried connecting each to the build array function and checking concatenate.  That just combined two ten digit arrays into a 20 digit array containing a bunch of zeros.

[RavensFan]

Yes.  And did you read my second sentence?

[chazzchuzz]

Oops sorry didn't notice it.  Is there any way to tell the program to delete the zeros automatically and shift the remaining data up?  When completed my program will have to deal with very large arrays. 

[RavensFan]

No there isn't an "automatic" way.

An alternative is to delete the zeroes from the array before concatenating them together.

Try using a select function if the value is zero pass the default value or use build array and add the new value to the array.

As RavensFan Explained, first you need to concatenate the arrays and then search for zeros and delete them from array.

Attached below is the snippet, Check if this codew works for you.

This ought to do it:

(See attached)

No need to size the second array since it is the same size as the first array (if I understand you correctly).

I don't know if it's the most efficient, but it's at least a small diagram.

(This may be your first suggestion in your post, gnshmrthy.)

I may oversimplify things a bit but if the arrays are always as shown (same numbers of items and always one and only one of the corresponding element zero) why don't you just add them?
