[Scilab-users] Re : problem with matrix of polynomials

[sgougeon at free.fr]

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.

Samuel
