Another way to do a stft but with fft from matlab

使用S变换成功实现了小电流接地系统的故障选线，仿真证明选线判据真实可信( S transform based fault line detection)

基础卡尔曼滤波。附有滤波初始条件，适合初学者(Basic Kalman filter. With filter initial conditions, suitable for beginners)

matlab软件上的数字图像处理基础源程序(digital image processing programs)

OFDM使用ifft加入CP的子函数。能够和其他函数并行使用，并被调用。(Joined CP in OFDM using ifft Functions. And other functions can be used in parallel, and was called.)

说明：  24篇matlab论文，matlab数据文件输入输出，用户界面编程，以及实例论文(24 papers matlab, matlab data file input and output, user interface programming, and example papers)

说明：  用Matlab语言实现线性方程组的全主元三角分解法.PDF(using Matlab linear equations of all the main yuan triangular decomposition. PDF)

则卡尔曼滤波的算法流程为： 1.计算预估计协方差矩阵2.计算卡尔曼增益矩阵3.更新估计4.计算更新后估计协防差矩阵(The Kalman filter algorithm processes as follows: 1. Calculate pre-estimate covariance matrix 2 calculate the Kalman gain matrix 3 updated estimate calculated after 4 update estimated defend difference matrix)

If the used buffer size is smaller than the actual buffer size, regenerate the lookup table and write the new table to the file.

将Matlab复杂语言转化成C语言开发,并且将转化的语言进行进一步的优化(To change Matlab into C，and make the change more super and simply)
