产生QPSK信号，根据仿真的数据估计差错概率(Produce QPSK signal and estimate the data according to the error probability)

基于matlab的fft算法设计，由于matlab的fft是built in文件，在此提供一种编写fft算法的思路。(Based on the matlab fft algorithm design, as the fft matlab file is built in, this provides an idea of ​ ​ writing fft algorithm.)

说明：  在很多图像处理的过程中，需要判别一个图像的清晰度，和图像分割结果的优劣，于是就引出了信息熵的概念，绝大多数时候，它都被用来作为评价图像的一个量化标准。(In many image processing processes, it is necessary to distinguish the clarity of an image and the result of image segmentation, so the concept of information entropy is introduced. Most of the time, it is used as a quantitative standard to evaluate the image.)

基于帐篷定理的计算矩形巷道中接受点功率大小的仿真(Theorem based on the calculation of rectangular tunnel tent to accept the size of the simulation point of power)

numerical code for matlab analytical bisec differentiation F FALSEPOS fixedpoint

说明：  旋转图像，平滑会出现的锯齿，例子和源代码(Rotate the image, smoothing jagged occur, examples and source code)

MATLAB中数值分析如拉格朗日插值、牛顿法求解方程组、LU分解等(MATLAB numerical analysis such as Lagrange interpolation, Newton' s method for solving equations, LU decomposition, etc.)

提取海洋二号卫星高度计的时间、经纬度、目标参数的程序，批处理版。输入时间、经纬度范围。(II satellite program to extract ocean altimeter time, latitude and longitude, target parameters, the batch version. Enter the time, latitude and longitude range.)

基于Davenport谱与谐波叠加法，生成脉动风速。(Based on Davenport spectrum and harmonic superposition method, generate pulsating wind speed.)

本人是做量化交易的，这个是进入行业的基础，通过matlab测算所有的均线对股票的影响，这个是用来测试ETF和IF的。可以通过这个M文件知道哪个是最优均线(I do quantitative transaction, this is the foundation of entering the industry, through matlab to calculate all the line influence on stock, this is used to test the ETF and the IF.Can use this know which is the optimal average M file)
