By the way, while it was possible in Scilab 5.5.2 to assign the elements 
of a list to all elements of the field of an array of structures, it is 
no longer the case in Scilab 6.0:

--> clear s
--> s.a = %pi;
--> s.b = "a";
--> s(2).a = %e;
--> s(2).b = "b"
  s  =
2x1 struct array with fields:
    a
    b

--> setfield("a", list(%i, 3.1), s)
setfield:  Wrong type for input argument #3: List expected.

In Scilab 5, we get the right assignment:

-->setfield("a",list(%i,3.1),s)
-->s.a
  ans  =
        ans(1)
     i
        ans(2)
     3.1
-->s(2).a
  ans  =
     3.1

This Scilab 6 restriction weakens the usage of arrays of structures.
