S变换 C语言程序 由R.G.Stockwell 编写 包含了正反变换 以及希尔伯特变换正反变换(S transform C language program prepared by the RGStockwell contains both positive and negative Hilbert transform, as well as positive and negative change)

说明：  Quick Sort an implementation in c++language. may it help others in their projects

西门子仿真编程软件S7-PLCSIM V5.4，用于S7-300/400系列PLC程序的仿真(S7-PLCSIM V5.4 offers the following new features with this release: DP, Industrial Ethernet and PC Internal connection types supported in addition to MPI Formerly, S7-PLCSIM used a default connection of MPI, address 2. With S7-PLCSIM V5.4, you can browse STEP 7 projects and select a networked node for establishing a simulation connection. S7-PLCSIM simulates the CPU of the selected node, all nodes that belong to that CPU, and the subnet of the selected node. Increased number of blocks supported for simulation S7-PLCSIM supports a set of OBs, SFBs, and SFCs as described in the electronic manual and online help. Of these, some are NOPs that is, they do not perform any operation. With S7-PLCSIM V5.4, the number of blocks that are not NOPs has increased.)

说明：  希尔伯特变换,用来求某一信号的相位。很好用的。(hilbert transform)
