最小二乘法的c语言程序，能求解多元方程组，具有良好的效果(The C language program of the least square method can solve the multiple equations. It has good effect.)

BP神经网络用于函数拟合与模式识别，研究生时的现代信号处理的作业，包括数据分析、绘图等等。( BP neural network function fitting and pattern recognition, Modern signal processing jobs when the graduate, Data analysis, plotting, etc..)

The solver was mdae to solve the teat tansfrer fields with cooling and hot zone. The Gauss-seidial, ADI, Laasonnen, and Crank-Nicolson schemes are present in the code. You can handle the method you want, iteration and the level of tolerance. The code was made at the LINUX platform. Let me know if you need assistance.
