because the way you have defined f(l), l is a 1x1 matrix but when you
want to estimate f(l), l is a 1xn matrix so scilab is confuse with * and
/ in f definition since this operations are not "element wise" for
matrix ... then you have two possibilities :

- replace * by .*, / by ./  in f definition
- use feval(l,f) instead of f(l)
