interpoltae a 1D array to get a different 1D array size

[tst]

If you want to do a real interpolation (make the new elements have different values than the existing ones), then you can use the interpolation function and do something like this:

If you just want to pad out the array, you can modify the VI posted <a href="http://forums.ni.com/ni/board/message?board.id=170&amp;message.id=133867#M133867" target="_blank">here</a>&nbsp;to work with a 1D array.
To learn more about LabVIEW, I suggest you try searching this site and google for LabVIEW tutorials. <a href="http://cnx.rice.edu/content/col10241/latest/" target="_blank">Here</a>, <a href="http://zone.ni.com/devzone/learningcenter.nsf/03f7c60f17aad210862567a90054a26c/55974411828f779086256ce9007504bd" target="_blank">here</a>, <a href="http://www.mech.uwa.edu.au/jpt/tutorial/index.html" target="_blank">here</a>, <a href="http://www.iit.edu/~labview/Dummies.html" target="_blank">here</a> and <a href="http://www.upscale.utoronto.ca/GeneralInterest/LabView.html" target="_blank">here</a> are a few you can start with and <a href="http://www.fafiles.com/" target="_blank">here</a> are some tutorial videos. You can also contact your local NI office and join one of their courses.

If you have LabVIEW 8.0 or later, there is "interpolate 1D" which is very flexible (e.g. x-values in input and output don't need to be evenly spaced, large choice of interpolations (linear, spline, etc.)).
An implementation for a simple linear interpolation is shown here, modify as needed.

Please tell me that you do not have controls set to appear as icons on the diagram. :smileysad:

I am almost too embarrased to admit that I haven not really touched the LabVIEW options since installing on a new PC a few weeks ago. So, yes, they're set to show as icons at the moment, the default behavior. ;)
For illustrative purposes, such as in a code image as above, it probably adds a little bit of clarity to the diagram picture. :)
(In my own code, I rarely use icons).
