matlab gui实例，实现时间的实时显示，包括年月日(matlab gui example, to achieve real-time display of time, including years at)

说明：  希尔伯特变换代码，用于求解超声波形包络线。并且有平滑处理(Hilbert transform code for solving ultrasonic envelopes. And smoothing)

In Matlab 模拟与分析PCM不同量化级别的量化噪声 可以直接运行(In Matlab， simulation and analysis of different quantization levels of PCM quantization noise ，can be run directly)

原始单纯形法（大M法，无需给出初始基变量）。输入：C是n维行向量，A是m*n的系数矩阵，b是m维列向量 输出：x最优解（如果有的话），fval最优值，flag解的状态说明，interation求解时的循环次数(The original simplex method (big M method, without giving the initial basic variable). Input: C is the n-dimensional row vector, A is the coefficient matrix of m* n, b is the m-dimensional column vector Output: x the optimal solution (if any), fval optimal value, flag state solution description, interation when the number of cycles to solve)

利用burg和Levinson-Durbin算法，根据100年间每年12个月记录到的太阳黑子出现次数的平均值求太阳黑子的活动周期(Burg and the use of Levinson-Durbin algorithm, according to 100 years, 12 months a year recorded the average number of sunspots appear for the activities of sunspot cycle)

这个是matlab中的二次型时频表示的全部代码。(this is the Matlab quadratic time-frequency representation of all the code.)

实现扩频里随机信号和伪码序列的产生，以及关于生成扩频序列的MATLAB程序，并用载波信号实现2PSK调制,在接收端用非相干积分实现捕获以及虚警概率的计算(Spread spectrum signal generated in the realization and pseudo random code sequence, and generate MATLAB program about spreading sequences and achieve 2PSK modulated carrier signal used to calculate the receiving end with a non-coherent integration to achieve capture and probability of false alarm)

生成一个矩阵的功能，主要是为了方便，可以直接下来用(Generate a matrix of functions, mainly for convenience, can be used directly down)

一个稍微复杂的多体动力学实例 包括动画演示等文件 主文件为main_ok (A more complex multi-body dynamic animation examples, including the master file and other documents as main_ok)

基于matlab的ofdm系统仿真，通过仿真实现了ls 和LMMSE准则的信道估计，并仿真比较了两种方法的性能(Matlab ofdm systems based on the simulation, the simulation criteria to achieve the ls and LMMSE channel estimation, and simulation performance of the two methods compared)
