this is a matlab code for computing DTW(dynamic time warping) for speech processing applications.

signal+noise is very simple like this

该程序用matlab写成，已包含vof（根据Hirt的方法）内容，但该部分尚不成熟。对于不包含自由面的计算比较成功。(The program written with matlab, included vof (according to Hirt' s method) content, but that part is not yet mature. For the calculation of the free surface does not contain more successful.)

实现基于PSO的混合粒子优化算法,具有很好的稳定性和快速性(Search algorithm based on hybrid particle swarm optimization algorithm based on TSP)

该程序可以进行扇形的短扫描重建，利用Parker加权函数。得到不错的重建效果。希望对大家有帮助。仅供参考！(This programme is a short-fan reconstruction.On the use of Parker weight function.I hope it will be useful.And the result of this programme is good.)

说明：  4种光束动画,FLASH素材,FLASH源码,FLA格式(Four kinds of beam animation, FLASH material, FLASH source, FLA format)

说明：  维纳噪声抑制 分辅助观测数据中漏入观测信号和不漏入观测信号两种情况讨论(Wiener noise suppression sub-assisted observational data leak into the observation signal and the signal does not leak into the observation to discuss two cases)

triangle wave generation using matlab

matla实现史密斯圆图的精确绘制，可直接运行，包含1个m文件(matla Smith chart to achieve accurate mapping can be directly run, including an m file)

基于matlab的脉冲时间信号表示与分析，对信号分析很有帮助(Representation and analysis, signal analysis based on matlab helpful pulse time signal)
