单自由度任意时程荷载响应分析
说明: 已知单自由度受迫振动体系的运动方程的解,是由齐次方程的通解与特解组成。其次方程的通解在无阻尼、临界阻尼、低阻尼、超阻尼中各有不同。(It is known that the solution of the motion equation of a single degree of freedom forced vibration system is composed of the general solution and the special solution of the homogeneous equation. Secondly, the general solution of the equation is different in undamped, critical damping, low damping and super damping.)

一维热传导方程_有限差分
分层的一维热传导方程的有限差分法MATLAB程序,是简单的显式差分格式,尽量使用了矩阵运算,没有符号运算。
文件chafen1.m以路面为例,假设有多层建筑材料,热传导系数已经在代码中给出。用户使用时请按自己需要修改chafen1.m文件,增减层数,修改热传导系数等即可。(One-dimensional heat conduction equation finite difference method MATLAB program, is a simple explicit difference format, as far as possible use of matrix operations, no symbolic operations
The file Chafen 1.m takes the road surface as an example, assuming that there are multiple layers of building materials, the thermal conductivity is given in the code. Users should modify the Chafen 1.m file according to their own needs, increase or decrease the number of layers, modify the thermal conductivity and so on.)
