<font size="4">Currently I'm not using the ODE solvers but it's an
area of interest since mathematical modelling is the core of my
business. I'd like to see that in Xcos I can get the full range of
ODE solvers (at least for 'real-only' as distinct from
'complex-number' issues).<br>

I don't regularly use ODE solvers for the time being, but I
think any improvement is valuable and is worth the effort. The
lack or paucity of feedback in this list is not an evidence of
lack of interest for the Scilab users community. It may also
encourage other potential users to move to Scilab. I'm grateful
for your effort and feel reassured that in the event I need the
feature, I'll have better solvers.<br>

<p>Hello,</p>
<p>Did anybody give a try to the Windows build ?<br>
</p>
<p>Frankly speaking, if nobody cares about improved numerical
methods in Scilab, things can be left as is, and time could be
spent on other features (but not by me...).</p>
<p>I can also prepare a Linux build, if users of this os want to

<p>Hi all, <br>
<br>
The next version of scilab will include a new module
"Sundials". This module provides new full featured ODE
solvers: arkode(), cvode() and DAE solver ida(), all
handling complex numbers and dense/sparse/banded Jacobians.
Each solver has specific features, e.g. ida() handles DAE,
arkode() handles mixed implicit/explicit Runge-Kutta methods
and cvode() can do forward sensitivity computation. <br>
<br>
The module also includes a general-purpose nonlinear system
solver: kinsol(), who takes advantage of the module
architecture (parsing, computation engine and SUNDIALS
abstraction of various linear solvers). <br>
