For people who don't want to pay for MathCAD, take a look at MathCAD express. There's no licencing cost, since they seem to be using it to get people hooked on MathCAD.
It can do everything with units, math operators and similar. It doesn't do the logic/programming side or some matrix stuff.
My company has a couple of MathCAD licenses, but half time time I'm just working with the express version because the licences are all checked out and it does what I need for most standard calcs. Printouts have a 'This was created using MathCAD Express' notice along the bottom, but it's not overly obtrusive.
If you keep a copy of it, it'll work forever. It doesn't need to phone home to work or anything.
Okay, I looked. It does matrix stuff. It doesn't do:
-Including of worksheets via reference (this is slightly annoying)
-Some of the functions for working with excel
-Advanced functions (Bessel, curve fitting, data analysis, differential equations, image processing, probability distributions, signal processing and statistics.)
-Symbolic evaluation
-Programming
-Templates (although you can just save a file and use it as a template manually)
Mathcad Express is the free version of Mathcad Prime.
Another alternative is Studyworks, which was a stripped down version of Mathcad, circa v2001, which you can sometimes find on eBay for around $10. While it's ancient, it does do units, matrices, numerical integrations, etc. Slightly more capable that Mathcad Express, I think, and substantially faster loading.
TTFN (ta ta for now)
I can do absolutely anything. I'm an expert!
Thank you IRstuff, TLHS, johnie134.
I actually own MathCAD Prime, but only use the MathCAD 15 portion of it. Every time I am trying to use it, I end up spending hours with the PTC support team fixing problems with the license file. I will give up on it and to to SMath or Excel or both.
