[scilab-Users] RE: Simulate the quarter-car model

[Berns Buenaobra]

Yes Mike!

No pain to gain! There is always the learning curve - students must continue
to make small steps on a steep slope other wise they will continue to slide
back. Scilab can be a good solver but the modeling part needs a human brain.
I wonder how one can defend an project or thesis if its done by some one
else.

To attempt is already the first sign of success!
