I need a calculus with matrices:
I tried this:
M=[2 , 0;0 , 1]*m
K=[3 , -1 ; -1 , 1]*k
| w^2 * M + K |=0
w=> (|w^2*[2, 0; 0, 1]*m + [3, -1; -1, 1]*k|) == [-3, 1; 1, -1]^0,5*(0,7071k + 0,7071)*[0,5, 0; 0, 1]^0,5/m^0,5
But this is not the correct answer.
After I tried to calculus this:
-5*y^2+2*y^4=0
y=> # Numerical solution exceeded max iterations (60)
and I didn't get a correct answer.
Someone can help me?
Thank you
