MATLAB

MATLAB (Matrix Laboratory) is a Programming Language.

General Commands:

whos returns a list of all variables Calling a .m file without the suffix runs it

State Space Model:

For the example:

$$\begin{array}{c}M\frac{d^{2}y}{d{t}^2}+C\frac{dy}{dt}+Ky=f(t)\\ \dot{x_1}=x_2\\ x_2=-\frac{C}{M}{x}_2-\frac{K}{M}{x}_1+\frac{f(t)}{M}\end{array}$$

We can represent this in matlab with:

function xdot = msdmodel(x,f)
 
xdot(1) = x(2);
xdot(2) = -K/M*x(1) - C/M*x(2) + f/M;
