Hola,
 
al construir una lista y buscar el maximo y el mínimo, no me devuelve el valor de la lista hasta que no ejecuto sobre la lista la media (devolviendo una lista de warnings).
¿Por qué ocurre esto?
 
ma:makelist(random(10),i,1,6);
maxi(ma);
 
[0,6,9,0,9,4]
(%o5) maxi([0,6,9,0,9,4])
 
/* [wxMaxima: input   start ] */
mean(ma);
maxi(ma);
/* [wxMaxima: input   end   ] */
