How to eliminate or remove zeros from 1D array

Question

How to eliminate or remove zeros from 1D array. Let say I have 1D array having foolowing elements
"0 0 0 0 0 4 0 0 9 0 0 1 4 0 0 0 0 0 0 0 0 10 9 0 0"
So after removing or eliminating zeros it will become as follow
"4 9 1 4 10 9"
So can any body guide me how can I do that? See attached Image for details.
Thanks

Here are 2 example .vi's I made based on altenbach's removeZeroes.png in this discussion thread: 
It seems pretty pointless to post those because no new useful information is given.
Currently, only the input is defined in the connector pane, making them useless as subVIs.
unlike my example using integers, an "=0", like any "equal" comparison, is potentially dangerous with DBLs.
Reshaping a 2D array to 1D before removing zeroes is pretty pointless because a 2D output cannot be recovered. A more interesting scenario would be to remove some columns or rows (e.g. that are all zeroes) from a 2D array.
You should also clean up the front panel, e.g. properly zero the upper left corner, make the controls/indicators nicely labeled, sized and arranged, and maybe even add scrollbars to the arrays.
Thank you for those comments.
Now the input and output are defined (in the updated attachments) for use as example subVI's.  I also cleaned up a few visual details, but I leave the rest for others to cater to their specific uses if they don't want to use this as a subVI (or at least as-is), such as changing the icons or changing to integers instead of doubles.
I'm not sure about what you mean exactly with "=0" being "potentially dangerous with DBLs".  I'm guessing you had a certain case scenario in mind.  Although the subVI's seem to work fine within my larger program and situation, my situation may not generalize with regards to this point.
I reshaped from 2D to 1D, with a 1D output, because it could be helpful for things like when later processing just needs a 1D array.  For example, in my situation I had to remove a huge spike of unnecessary "0"'s from a previous subVI that were affecting the output display of a certain histogram.  So it turned out a 1D array output was helpful, and you never know what problems come up, so I included the 2nd example.
Hopefully if someone is looking for this, they can just use or play with an example subVI (granted that they know how to plug things in for their context).  I was hoping to post a subVI people could put to direct use.
