基于MATLAB的最优化算法代码和实验报告.rar
【实例简介】这是我以前最优化课的实验报告,希望对大家有所帮助。
用MATLAB求解无约束的问题,主要有最速下降法,牛顿法,共轭梯度法,变尺度法(DFP和BFGS法),非线性最小二乘法。
用MATLAB求解有约束的问题,主要是外惩罚函数和广义乘子法。
以及一些对具体问题的分析,MATLAB的代码在文档里都有。

单片机实现信号发生器原理图和源代码
利用AT89S51和DAC0832实现的函数信号发生器,可产生方波,正弦波、三角波以及锯齿波。并可以实现调频和调幅两各功能,而且可频率实时显示.绝对原创.2011.5.21 现在已转软件开发,今天看到大家反应太贵,现下调到了5分,然后根据原理图焊板时请在P0口加上上拉电阻,不然得不到输出波形
