Hello, I want to solve the equation:
for s. In this equation M, C and K are big (at least 100x100), sparse matrices and C depends on s (it has the term (50/(s+50)) in it). Is there a faster way to solve this besides the following procedure?:
- using the symbolic variable "s"
- finding the determinant with the command det(s^2*M+s*C(s)+K)
- solve the equation using the command solve(det(s^2*M+s*C(s)+K==0,s) and then
I tried to use polyeig(s^2*M+s*C(s)+K) as an alternative, but it just solves the equation for a constant C and not for C(s).
