discuss the cooling of a circular fin by means of convective heat transfer along its length. Convection gives rise to a temperature-dependent heat loss or sink term in the governing equation. Shown in Figure 4.9 is a cylindrical fin with uniform crosssectional area A. The base is at a temperature of 100°C (TB) and the end is insulated. The fin is exposed to an ambient temperature of 20°C

灰色预测，简单的编程，大家多提意见(Gray forecast, a simple programming, we do so!)

分数阶fourior变换的源码，主要用来处理线性调频信号(fractional fourior transform source code, is mainly used to treat LFM)

说明：  通信系统中一种常见的数字调制方法，16—QAM调制(QAM)

说明：  对于给定的200组数据用基本最小二乘算法辨识其确定的差分方程系数(For a given set of data with 200 basic identification of least-squares algorithm which determines the differential equation coefficients)

频率估计问题一直是研究的热点。此为一个相位差法估计频率的程序代码，可供学习参考。(Frequency estimation has been the research focus. This is a phase difference method to estimate the frequency of the program code, for learning reference.)
