Hello guys!!
i need to find the space rapresentation( matrix A, B ,C. D) for this system:
m1 = 1;
m2 = 1;
m3 = 1;
k0 = 100

Aha! Now I understand your fundamental issue. Your mathematics teacher should have covered this matrix topic.
Were you provided with this state-space information in your previous Question? The code for describing the full state-space was also provided in my Answer. I hope you have checked it out thoroughly, not simply brushed through it. The equations in your image represent just a portion of the full state-space, which is boxed in red in the image below.
I actually wonder why your math teacher taught you Kalman Decomposition Matrices first, before teaching you the "State-space representation of scalar differential equation systems." Try working with my code, and then paste your code here.

It's good to be cautious when dealing with engineering problems. If you are working in a simulation environment, you can test your ideas and perform an analysis on the system to evaluate whether the designed observer is effective or not. If you encounter any difficulties, please remember to share your MATLAB code so that practitioners in the Control System Toolbox can help with the checking.
