Hello Federico,
cond() and rcond() do not accept rationals, but the determinant of A is very
close to 0:
--> det(A)
ans =
3.573D-10
------------------------
0.0000027s² +7.433D-10s³ This likely explains that the inversion is not reliable. Regards Samuel _______________________________________________ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users
