Calculates the response of multi-degree of freedom nonclassicaly damped linear system subjected to dynamic forces. (using Newmark's method)

function Result=Newmark_Linear(M,C,K,f,fs)

Input
M:mass matrix (n*n)
C:damping matrix (n*n)
K:stiffness matrix (n*n)
f:external force matrix(n,N)
fs: sampling frequency
where n is the number of degrees of freedom, N is the length of data points of dynamic force

Output:
Result: is a structure consist of
Result.Displacement: Displacement (n*N)
Result.Velocity: Velocity (n*N)
Result.Acceleration: Acceleration (n*N)

Thank you so much. The code does not plot the displacement, velocity and acceleration in a graph, and I can't get it to function. Can somebody help with the code to this figures?

Quick implementation and easy-to-use MDOF code. Thanks a lot, much appreciated your work.
