[Scilab-users] Solving a ecuation

[Chuox]

I need to solve the following equation

det(Kx-w*M)=0, Were Kx, and M are know matrix, in my texas vollage 200 (R) i
solve it like this:

Kx=


    457458.17  - 187960.85    0.           0.           0.         
  - 187960.85    386294.62  - 198333.77    0.           0.         
    0.         - 198333.77    269758.49  - 71424.72     0.         
    0.           0.         - 71424.72     100135.95  - 28711.232  
    0.           0.           0.         - 28711.232  - 28711.232  

M=

    457458.17  - 187960.85    0.           0.           0.         
  - 187960.85    386294.62  - 198333.77    0.           0.         
    0.         - 198333.77    269758.49  - 71424.72     0.         
    0.           0.         - 71424.72     100135.95  - 28711.232  
    0.           0.           0.         - 28711.232  - 28711.232  


det(Kx-w*M) and i get an ecuation in fucntion of w like this:

-769068340073*(w^5-6240.278*w^4+13359439.553*w^3-11742579744.9*w^2+3.7606*10^12*w-2.67*10^14)

Then:
solve(-769068340073*(w^5-6240.278*w^4+13359439.553*w^3-11742579744.9*w^2+3.7606*10^12*w-2.67*10^14)=0,w)

The following results:
w=98.064 or w=484.37 or w=1261.711 or w=1596.79 or w=2799.33

I dont even know how to solve the last equation in SciLab.

Thank a lot!
