I am currently following along with the SMath Primer and have run into an issue with vector operations on page 26 of the pdf.I am using the range 2 & 3 functions but SMath tells me they are undefined. Is this a known bug or what am I doing wrong? I am currently using Version .99 Build 7030

There are many more ways to range/discretize.

I Can reproduce SS 6179, but [range] in 1*1 matrix is wrongdoing.

Is there an issue with having two instances of SMath open at once? I closed the software and reopened it at home and it worked fine. Thanks for the help!

NO such issue was reported ... proof:
Open Smath from fresh Win 10 ... work my stuff.
Download work sheet from the Forum ... as many as you want.
Those download are new instances, all working independently.

There is/are no technical justification to open several Smath instances.
It computes the displayed document ... same as Mathcad.
In other words: multiple instances don't multiple compute.

This one looks really interesting and difficult at the same time. I am in my Thai condo trying to solve it too, thank you for sharing
