Here we present some MATLAB programs which solve the second
problem of Dynamics:
* Derive differential equations, resolve them analytically or numerically, and plot the relative graphics.
* There is no necessity to write a procedure-function for the derivatives! It is generated automatically.
* You can choose in-line the most proper Solver to your problem.
* All the data can be input from data files or in-line mode.
* You can run these programs repeatedly with different values of some parameters p1, p2, ..., and ini-conditions without restarting them.
* The programs are applying in the laboratory tutorials with the students of Mechanical Engineering in Technical University at Gabrovo, BULGARIA.
* These programs are written in accordance with plans of SCOPES PROJECT No 7 IP 65642 - Establishing CSE in Bulgaria and Macedonia.
