d

^{2}X/dt

^{2}+ (2H)dX/dt + (E)X = 0

where 2H and E are 3x3 matrices and X is a 3x1 column vector.

The solution I have is

d

^{2}x/dtau

^{2}+ (2wH)dx/dtau + x = 0

where w is equal to the square root of the inverse of E, and x and tau are the new parameters.

I will upload a photo of all my steps if necessary, but I really just wanted to know if this problem can be approached exactly the same way as you would for a second order system with scalar parameters.

Thanks!
