I would simply like to define a vector, then apply a operation to each element and have the results in a second vector. This seems to be simple in MathCad but I can't seem to get it in SMath Studio.

The result is the sum of the squares of the elements, multiplied by two.
As far as I know SMath does not support vectorization (yet) so, in order to obtain what you need, you should use a for loop.

If you are using vectors, then you can try mat2sys() and sys2mat()

Thank you mb10, I got the For..Loop to work it out. I was wondering if the vector options were available or not.
To omorr, the mat2sys() and sys2ma() looks like a clean method to acheive these functionality but how do I add the mat2sys() and sys2mat() functions?
Thank you.

mat2sys and sys2mat are part of the CustomFunctions plugin by Davide Carpi. You can install it using the extension manager (Tools> Plugins) or use the unofficial distribution with pre-installed plugins (link in the signature).
You also might consider using the Maxima Plugin (which requires Maxima to be installed on your system)
