本matlab程序用共轭梯度法来求解多元模型的最小值（给出最小值和精度情况）-The matlab program conjugate gradient method to solve the minimum multivariate model (given the minimum and the accuracy of the situation)

共轭梯度法，一种适合于研究生最优化方法课程的小程序，基于matlab的一个算例仿真-Conjugate gradient method, which is suitable for most graduate programs applet optimization, simulation based on a study of matlab

使用最速下降法和共轭梯度法实现优化功能，基于MATLAB平台使用m语言编写(Based on the MATLAB platform, steepest descent method and conjugate gradient method are used to achieve the optimization function with M language.)

基于MATLAB编写的大地电磁二维有限单元法正演程序，矩形单元剖分，线性插值， 使用说明： 1. 运行MT2DMODEL.m构建正演模型 2. 运行TMmodel.m和TEmodel.m正演计算，计算结果自动保存 3. 程序进行了优化，并将BICGSTAB（稳定双共轭梯度法）用于求解线性方程组，求解效率提高，一般情况下正演计算仅需1~2秒(Based on MATLAB compiled two-dimensional magnetotelluric fin
