大学时候跟导师做的一个暂态电磁场数据分析的程序，用于自动检测和识别波形数据中的脉冲起始时间等参数(University instructors often do with a transient electromagnetic field data analysis procedures, for the automatic detection and identification of waveform data pulse parameters, such as start-up time)

Reconstruction of magnetic resonance images from data not falling on a Cartesian grid is a Fourier inversion problem typically solved using convolution interpolation, also known as gridding. Gridding is simple and robust and has parameters, the grid oversampling ratio and the kernel width, that can be used to trade accuracy for computational memory and time reductions. We have found that significant reductions in computation memory and time can be obtained while maintaining high accuracy by using a minimal oversampling ratio, from 1.125 to 1.375, instead of the typically employed grid oversampling ratio of two. When using a minimal oversampling ratio, appropriate design of the convolution kernel is important for maintaining high accuracy

是用Matlab求得自相关函数的源代码，对刚接触自相关互相关方面的同学有很大帮助！(Is the autocorrelation function obtained using Matlab source code for the new to the inter-related aspects of the autocorrelation of great help to the students!)

很多情况下不能直接将目标函数作为适应值函数，此时需要对目标函数进行标定。(In many cases the objective function can not be directly used as fitness function, then the objective function needs to be calibrated.)

The function to obtain indexes of inner of window points in the windoving procedure for each point in 2D surface. It allows to avoid cyclic operation which too slowly.
