<br><font size=2 face="sans-serif">Has anybody looked at Nick Trefethen's
Chebfun project?</font>
<br><font size=2 face="sans-serif">It's matlab - the concepts would map
to scilab in a straightforward way.</font>
<br><font size=2 face="sans-serif">This would be a large but not too complex
project.</font>
<br>
<br><font size=2 face="sans-serif">The idea is to manipulate generic functions
by means of their chebychev expansions.</font>
<br><font size=2 face="sans-serif">All the usual operators are overloaded
so the syntax is easy to master.</font>
<br><font size=2 face="sans-serif">This approach allows a numerically-based
package to achieve result normally reserved</font>
<br><font size=2 face="sans-serif">for symbolic tools.</font>
<br>
<br><font size=2 face="sans-serif">Googling Nick Trefethen Chebfun gives
lots of examples and info.</font>
<br>
<br><font size=2 face="sans-serif">Question -- are there resources to apply
to such a project?</font>
<br>
<br><font size=2 face="sans-serif">Thanks,</font>
