分数阶傅立叶变换程序 Fractional Fourier Transform(Fractional Fourier Transform)

计算了沿CMPL厚度方向，可以看出，CMPL的界面从第一个网格移动了1/4个网格，这是为了保证，CMPL更新的电场和磁场的数目相同。(The thickness direction along CMPL is calculated.It can be seen that the interface of CMPL moves 1/4 of the grid from the first grid to ensure that the number of electric and magnetic fields updated by CMPL is the same.)

用matlab编写的关于流场测速的一个Demo,处理速度较快、匹配位置准确。(The URAPIV Toolbox contains a set of command-line functions to import, post-process and analyse 2D vector fields from LaVision s DaVis PIV (particle image velocimetry) software. It enables to handle and perform operations over large amount of velocity fields, and to produce high-quality vector/scalar outputs. )
