matlab编写的声卡采集声音信号并可以播放出来的gui界面。(matlab write sound card and can play sound signals collected from the gui interface.)

dfa 时间序列的赫斯特指数的计算线性趋势的拟合

This is a compact code for reliability analysis based on the stochastic response surface method (SRSM) which first uses the univariate dimension reduction (UDR) to decompose the multidimensional performance function into multiple one-dimensional univariate functions and then employes the cubic spine interpolation to approximate the one-dimensional univariate functions.. One mathematical example is solved for demonstration purpose.

phase its about phase of a signal or imf that you can find it for another things also in this code you can fine the amplitude of a complex number

这个例子显示了一个静止同步补偿器（STATCOM）用于中点电压调节的500千伏输电线路。(This example shows a Static Synchronous Compensator (STATCOM) used for midpoint voltage regulation on a 500-kV transmission line.)

DOA 中的DML,DML为确定性最大似然算法，具有估计精度高、抗噪性强的优点(In DOA,DML is a deterministic maximum likelihood algorithm, which has the advantages of high estimation accuracy and strong anti-noise)

说明：  利用潮位数据计算理论深度基准面，其中各分潮系数需修改(Calculating theoretical depth datum using tidal data)

To find and estimate of the best solution and parameter in our problem we can use the evolutionary programming. PSO (particle swarm optimization) is an applicable method to catch this target. In these files I show the Simple PSO that it can be base of solve complicated problem, the code could run by MATLAB.

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)
