光伏太阳电池的仿真，基本的数学公式与基本知识(PV solar cell simulink)

追赶法解数学方程，主要用于数值运算，希望对大家有帮助(Solving mathematical equations to catch up, mainly for numerical computation, we want to help)

说明：  认知无线电里的能量检测，适合初学者，比较简单(Energy detection in cognitive radio, suitable for beginners, is relatively simple)

ofdm and comb function

说明：  matlab遗传算法工具箱及应用，对于遗传算法中的通用问题和各种函数都给出了详细的参考。(MATLAB genetic algorithm toolbox and its application, for the general problems of genetic algorithm and a variety of functions are given a detailed reference.)

说明：  关于大型机的内容，是cobol语言，大家可以仔细研习(Content on the mainframe is the cobol language, we can carefully study)

主要内容(signal_analyzer.rar)如下： test1.txt 第一列为时间t，0.001s为步长；第二列为系统的输入信号；第三列为系统的输出信号。 signal_analyzer.m首先将test1.txt 的数据读入workspace，然后进行FFT，分析出两信号的频率，输出对于输入的幅值衰减（db），输出对输入的相位差。 (Main Content (signal_analyzer.rar) as follows: test1.txt the first time as t, 0.001s for the step the second as the input signal the third as the system output signal. signal_analyzer.m first test1.txt the data read into the workspace, and then FFT, the frequency of the two signals, the output amplitude for input attenuation (db), the output of the input phase difference.)
