- In my opinion, anyone who has used a real CAS will quickly get frustrated
- with MathCad. It is not easy to generate graphics (I'm sure to get a lot
- of responses on this that say: all you have to do is this...and this...and...
- but I only got poor plots out of it after trying several times. And surfaces
- are nearly impossible), it doesn't want you to define variables - only letters
- that are attached to fixed numbers. That may be useful to some, but it is not
- really computer-algebra.
-
- Those who use it tend to mention that the matrices are easier to enter than in
- Maple or Mma. That is true - but again, I don't think it'd handle variable
- entries easily. It is not extensible, not flexible.
-
- Even for typesetting, it does things its' way, not yours. Better to paste
- your TexForm output into a TeX document.
