@Brad805: thanks for the sample. I was considering asking someone if they could post a sample of what a dolled up, final form calc looks like in SMath. What you've accomplished would suit my needs with the grid turned off.
@Everybody: this thread is getting me close to the critical mass of interest that I need to look into this. I do have a few more questions:
1) Are there decent matrix/array handling functions?
2) Are there numerical equation solving algorithms like Solve Blocks in MathCAD?
3) Are there functions allowing one to display calculated data in a tabulated form?
4) Are their eigenvalue calculation tools?
5) What do we know about the longevity of the SMath enterprise? I don't want to sink a bunch of effort into switching over only to find that, five years from now, there's no more SMath because the developers graduated high school and got real jobs. Not that I trust MathCAD in the longevity department these days...
Yes, I could indeed conduct my own research to figure these things out if I were so inclined. I won't be any time soon.
