two comments:
Before the Macsyma Inc company gave up, it implemented what was
essentially Matlab (of that time, anyway).
From the documentation/ demo file:
"You can use Matlab commands in Macsyma in three ways:
Method 1. Macsyma can load Matlab language files.
Method 2. Translate Matlab language files into Macsyma language files.
Method 3. Type Matlab Commands to the Macsyma Window. "
This facility was not enough to keep the company from folding.
Could one have lured an actual Matlab user into using Macsyma instead?
Are one's favorite programs truly portable in such circumstances?
Are these questions relevant re Maxima+R projects?

2nd comment. I was not aware of Vernat's paper, (which for those who
choose not to spend the time to read it..) suggests that the speed
difference
between C and Lisp for some image processing tasks is negligible.
Thanks for pointing it out.
