LFM信号FRFT变换分析
线性调频信号(Linear Frequency Modulated,LFM)作为一种典型的非平稳信号而且具有大的时间-频带积,被广泛用于各种信息系统。从电子战和电子干扰的角度看,为解决作用距离和距离分辨率的矛盾以及提高信号的隐蔽性，通常采用LFM信号，对于线性调频信号的检测和参数估计,成为电子战研究的重点matlab计算分数阶傅立叶变换运用分数阶傅里叶变换frft对线性调频信号lfm参数进行估计，结果很准确例程完整，有运行结果。

迭代法计算一元非线性方程
应用背景
在计算方法中计算线性方程中。要考虑迭代格式的构造、初始条件的选取。收敛性。终止条件和误差分析。需要建立迭代函数，写出等价方程的不动点
关键技术迭代法计算一元非线性方程:f(x)是实变量x的非线性实单值函数，一元非线性方程是指f(x)是多项式的非线性方程。可以用迭代法获得F(x)=0的近似值
