S变换是一种时频分析方法，用于分析非平稳信号。(use S transform to process signal)

以matlab实作histgram equalizatuin(To implement histgram equalizatuin matlab)

深度学习matlab工具箱，已经测试通过的源码，可以应用在图像识别、模式识别、语音识别等领域(Deep learning matlab source code, which can be applied in graph identification, pattern recognition and sound recognition)

如关键词，本人搭建的，在matlab2016b上测试。(For example, keywords, built by myself, are tested on MATLAB 2016b.)

MPI参考手册 MPI Reference Manual 大家相互学习 (MPI MPI Reference Manual Reference Manual, we learn from each other)

matlab的几乎所有应用的 源码例程, 可以帮助读者全面掌握matlab(Almost all the matlab source application routines that can help readers grasp the full matlab)

this code simulate about capacity of mimo-antenna system.

程序利用小波分解将声音信号分解为高频与低频部分，而后利用软阈值方法确定高频与低频各自的小波重构系数，将高频与低频部分重构还原信号达到降噪的目的。(Program using wavelet decomposition sound signal into high and low parts, then use soft threshold method to determine the high and low frequency coefficients of each wavelet reconstruction, reconstruction of the high and low frequency part of the purpose of noise reduction signal reaches.)

说明：  旋转式永磁同步电动机的电压矢量PWM控制算法，可以作为比较参考。(Rotating permanent magnet synchronous motor voltage vector PWM control algorithm can be used as comparison reference.)
