I didn' try Octave.

I like Matlab, because it provides a lot of toolboxes and blocksets,
which helps when first approaching new stuff.
Simulink provides even automatic generation of VHDL code,
and it really works!

When it comes to precision of calculation, I found SciLab to be
superior.

Scripts are very similar - I indeed created scripts which run in 
both worlds (with some   if matlab then ... else ... constructs).

If your budget is low, use Scilab instead of Matlab. 
If you need special features, buy Matlab/Simulink, but benefit of 
your Scilab in parallel!
