I was playing around with SMath and trying to graph a piecewise function curve. I am receiving a "Type conversion error. Please contact the developer." message.

Any ideas what is causing that? version 0.99 (build 6884)

Hello,

the problem is that in boolean comparisions you are using matrices instead of scalars (in both arguments, x and um)

For plotting, if/otherwise is convenient. Generally, for maths: if/else.
[< ...>] are for while loops and some exceptional algorithm(s).
Observe the undocumented min(x).
For Derivation/Integration of discontinuous functions use FD [Finite Differences].
