The eigenvectors, would tell us about the different oscillation modes we could have. I prefer to let the Symbolic Math Toolbox do these derivations: %x1''=(F(t)-(c1+c2)*x1'+c2*x2'-(k1+k2)*x1+k2*x2)/m1, Eq1 = D2x1 == (Ftfcn-(c1+c2)*Dx1+c2*Dx2-(k1+k2)*x1+k2*x2)/m1, Eq2 = D2x2 == (c2*Dx1-c2*Dx2+k2*x1-k2*x2)/m2. Lets first turn the state space equations of motion into a Matlab function. If we took its eigenvalues, (and all the masses and spring constants were positive) we would find that we had four purely imaginary eigenvalues. Today, we'll explore another system that produces Lissajous curves, a double spring-mass system, analyze it, and then simulate it using ODE45. I can examine this problem if you have the opportunity to develop new data. You can go through the videos either before or after completing this tutorial. +918939888018 +918939888018.
