Application of MATLAB in the solution of dynamic equation
Cai Shi-dong · Journal of Guangxi University of Technology · 2006
At present,the numerical analysis method is mainly used to solve the dynamic equation.Its work on the programming is large,the process of computer is less efficient and the accuracy of results is less precise.The dynamic equation of the structure under external force such as earthquake is described by the state-space method,and simulated dynamically by using lsim function in MATLAB.A practical example is illustrated and shows that the solution of dynamic equation can be effectively and more accurately analyzed by MATLAB.
