<para>Esboo animado da funo x-->f(x,t) para t= theta(1) ,theta(2),
etc. f pode ser uma funo do Scilab ou uma rotina dinamicamente ligada
desde que y=f(x,t) seja avaliado como y=feval(x(:),t,f). Ver feval. A
funo f tal que x,t -> f(x,t) = <literal>R^N</literal> avaliada em
x= vetor de <literal>R^N</literal> e t=nmero real. x um N-vetor de
valores x e para cada t em theta, f(x,t)=N-vetor de valores y.</para>
