Solve the eigenvalue foe two matrix

[V,D]=eig[K,M],if the K and M matrix is the symoblic matrix, there is one variable in matrix, how to solve this problem.

Thanks!

What is your notation intended to convey ? Is it intended to convey that you have two symbolic matrices whose eigenvalues and eigenvectors are the same and you wish to solve for the value of the symbolic variable that gives that property?

If so then I would suggest using eig() on each of the symbolic matrices, and then solve() for the set of eigenvalues to be the same (remember, the order is not fixed), perhaps following up by cross-checking that the set of eigenvectors is the same.

this is a dynamic problem for vibration. two symbolic matrices whose eigenvalues and eigenvectors are not the same.

I only want to know the eeigenvector for these two matrix.

Thank you for your concern.
