线性方程组的cg解法matlab，可以用于cg方法来计算线性方程组(Cg solution of linear equations matlab)

本代码是对论文《Analysis of Cognitive Radio Networks with Imperfect Sensing》的仿真实现(This code is the thesis " Analysis of Cognitive Radio Networks with Imperfect de Corriente Flux-Gate Transducers simulation)

是一部不错的编码，值得很多人学习,都可以看看(Is a good code, it is worth a lot of people study, may have a look)

说明：  光伏阵列最大功率跟踪系统（光伏电池模型+扰动观察法+BOOST电路）simulink仿真系统。((PV system to achieve maximum power tracking via a boosconverters, and the control method is perturbation and observation))

灰色系统理论是研究解决灰色系统分析、建模、 预测、决策和控制的理论.灰色预测是对灰色系统 所做的预测.目前常用的一些预测方法（如回归分 析等），需要较大的样本.若样本较小，常造成较 大误差，使预测目标失效.灰色预测模型所需建模 信息少，运算方便，建模精度高，在各种预测领 域都有着广泛的应用，是处理小样本预测问题的 有效工具(Grey system theory is the research and solution of grey system analysis, modeling, The theory of prediction, decision - making and control At present, some commonly used prediction methods (such as regression score) If the sample size is small, it often results in a comparison Large error, so that the prediction of the target failure Less information, convenient operation, high modeling accuracy, in a variety of prediction collar Fields are widely used to deal with small sample prediction problems Effective tool)
