form_diag_manip(3)
NAME
form_diag_manip - concatenation on a product space
DESCRIPTION
build a form_diag on a product space.
EXAMPLE
- The following example builds a 3-blocks diagonal form:
- geo g("toto.geo");
space V(g,"P1");
space T = V*V*V;
form_diag Iv(V) ;
form_diag I(T) ;
form_manip I_manip;
I_manip << size(3) << Iv << Iv << Iv;
I_manip >> I;
