<para>Para utilizar <literal>showprofile</literal> a funo Scilab deve
ter sido preparada para profiling (anlise de performance) (ver
exec).</para>
<para>Para tal funo,Quando tal funo executada, o sistema conta
quantas nmero de vezes que cada linha executada e quanto tempo de cpu
gasto para execuo de cada linha. Estes dados so armazenados dentro da
estrutura de dados da funo. A funo <literal>showprofile</literal>
retorna resultados de profiling (ver <literal>profile</literal>) com o
texto das linhas da funo.</para>
<para>O texto da funo reconstrudo com
<literal>fun2string</literal>.</para>
