Hello, I am a beginner level in Matlab so I am little bit confused by this questions would you guys have a look please?
Thank you!
w^2 [ 3 0 0 (x) = [ 10 -4 0 (x)
0 2 2 -4 6 -2
0 0 1] 0 -2 2]

Still confused ? Then read about "eig".
B = [ 3 0 0 ;
0 2 2 ;
0 0 1] ;
A = [ 10 -4 0 ;
0 2 2 ;
0 0 1] ;
[V,D] = eig(A,B)
A*V - B*V*D
A*V(:,1)-B*V(:,1)*D(1,1)
A*V(:,2)-B*V(:,2)*D(2,2)
A*V(:,3)-B*V(:,3)*D(3,3)
w(1) = sqrt(D(1,1))
w(2) = sqrt(D(2,2))
w(3) = sqrt(D(3,3))

The V's are your x and the sqrt(D)'s are your w's. Or what do you mean ?

The problem is in terms of w^2 so to find w you need to take the square root of the computed coordinates
