当前工程上广泛采用了一种高效滤波器，即CIC（cascaded integrator-comb filter）将其作为第一级来实现抽取、低通滤波。第二级再用一个普通的FIR滤波器就实现使后端设备工作在较低的频率下且硬件花销少、功耗也很低。(Widely used in the current project, a highly efficient filter, that is, CIC (cascaded integrator-comb filter) as the first level to achieve the extraction, low-pass filter. An ordinary second-class and then the realization of the FIR filter so that the work of the back-end equipment at a lower frequency and spending less hardware, power consumption is very low.)

A PIV Post-processing and data analysis toolbox(The PIVMat Toolbox for Matlab contains a set of command-line functions to import, post-process and analyse 2- and 3-components vector fields from PIV (particle image velocimetry), stereo-PIV, DIC (digital image correlation) SS (synthetic schlieren) or BOS (background-oriented schlieren) applications. Main Features: - Import vector fields from PIV (Particle Image Velocimetry) or other related technics, such as DIC (Digital Image Correlation), SS and BOS (Synthetic Schlieren and Background-oriented Schlieren). - Compatibale with files from DaVis (LaVision), DPIVSoft (Meunier & Leweke), VidPIV (Oxford Laser), MatPIV and Optical Flow. - Standard vector field operations: interpolation, filtering (median, Butterworth...), averaging (temporal, spatial, azimuthal...), derivatives computation (vorticity, divergence, strain, Q-factor...) - Fully vectorized: all operations directly apply on arrays of fields (no for loops) - More than 60 functions with full on-line documentation sampl)

基于MATLAB的bpsk系统下的不同情况的中继选择(MATLAB BPSK system under different circumstances-based relay selection)

1:对于所有等级的隶属度之和为1。 2：输出结果随某个变量的增大而qdh1的结果呈现出单调递增或递减 3:最后的等级出[0.2 0 0 0.8]这种情况是正常的，和可拓评判中的对于等级的距离的概念是不一样的。 只表现有变量是属于0.2这个等级的。
