Consider a second order ODE . The output is y(t) and the input is x(t). THe coefficients A, B and C are constants. I have 8 data points y(t), i.e. 8 values of y for values of t between 0 and 1.75. How can I determine the values of the coefficients using the data in MATLAB?

You will also need to have collected x(t) at each sample point.
