Can you tell me how you solved the ode45 for equations of motion?
NST = 4;
MPF = length(NST);
Xg(t) = [.any values ok.] % Matrix size of 1880 X 1
x"(t) + 3.797*x'(t) + 1442*x(t) = MPF*Xg(t)
can you give me the code please.

ode45() cannot deal with those kinds of systems. Runge-Kutta solvers assume that the given equations have continuous first and second derivatives, but your Xg are impulse functions and so do not have continuous first derivatives.
