This seems to be simple in MathCad but I can't seem to get it in SMath Studio. In MathCad In SMath Studio I get this. I'm not shre just what this result is. Any assistance would be appreciated. Thank you.

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.

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.

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) Edited by user 16 October 2013 23:51:01(UTC) \| Reason: Not specified mkraska attached the following image(s):
