<pre wrap="">Hi,
I want to do the equivalent of
plot( xdata, xdata .^ 2, xdata .^ 3, xdata '^ 4, ... );
and benefit from the plot() color rotation, without having to repeat the equation.
In Perl I might do (something like):
plot( xdata, map xdata .^ $_, 2 .. 5 );
Something like that in SciLab?
</pre>
