I need to implement following equation in which A, B, C, D and x are matrices with variable parameters (i.e. parameter value changes with time).
X = Ax+Bu
Y = Cx+Du
It would be really helpful if anybody can guide me how can I implement these equations in Simulink?

The Control System Toolbox has a Discrete Varying State Space block and a version for Continuous time. These accept as inputs values for the A, B, C, and D matrices.

Thank You Benjamin for your response.
Is it possible to vary parameters' value of matrix A at run time? E.g. Matrix A contains cornering stiffness and vehicle velocity parameter. Can I vary their values with time using this block?
