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.)
