matlab 边界跟踪程序，图像要求为二值图像，输出为边界的点的坐标。(matlab boundary tracking procedure, the image requested for the binary image, the output for the coordinates of border points.)

This is Sift(Scale invariant feature transform) tutorial file. source cord was made based on matlab.

这是一个三次样条插值的.m程序 输入的是一个二维数组A(Nx2) 插值方法为: S(x) = A(J) + B(J)*( x - x(J) ) + C(J)*( x - x(J) )**2 +D(J) * ( x - x(J) )**3 for x(J) <= x < x(J + 1) (This is a cubic spline interpolation. M program input is a two-dimensional array A (Nx2) interpolation method: S (x) = A (J)+ B (J)* (x- x (J ))+ C (J)* (x- x (J))** 2+ D (J)* (x- x (J))** 3 for x (J) )

基于keystone算法的距离迁徙校正，用于SAR成像中插值运算(Migration distance keystone correction algorithm for SAR imaging interpolation)

用不同插值方法对数据进行一维插值，通过结果不难看出，不同的插值方法导致不同的插值结果(One-dimensional interpolation data with different interpolation methods is not difficult to see through the results of different interpolation methods lead to different interpolation results)

此例程为配套书籍的第六章例题6-9的相对应代码，功能为方波信号离散小波变换，编程环境为matlab。(This routine supporting books Chapter Example 6-9 corresponding to the code for the function square wave signal discrete wavelet transform, programming environment Matlab.)

malab的一本书。对于初学者比较有帮助(malab of a book. For more help beginners)

需要将音乐文件bhk_med.wav放于D盘根目录下才可以直接执行程序，或将程序中的音乐文件路径指向当前目的音乐所在的地址。背景音乐可以更换，甚至可以自行合成。(Music files need to be put in the D bhk_med.wav root directory before you can run the program directly, or to program the music file path to the address of the current purpose of music is located. Background music can be replaced, even on their own can be synthesized.)
