为了便于在matlab中调用susan算法的c实现函数，对Stephen Smith写的susan2.1 c源码进行简单编辑剪裁，并提供常用susan函数的matlab mex接口函数，使用者在matlab中简单编译后就能使用了。(Matlab in order to facilitate call susan algorithm realize the c function, written by Stephen Smith on susan2.1 c source code for simple cut editing, and provide common susan function matlab mex interface function, the user in a simple matlab compiler will be able to post use.)

读一组整数到vector对象，计算并输出每对相邻元素的和。如果读入元素个数为奇数，则提示用户最后一个元素没有求和，并输出其值。(Read a set of integers to vector objects, calculate and output, and each pair of adjacent elements. If you read an odd number of elements, the last element of the user is prompted no summation, and output its value.)

对图像进行非下采样小波变换，得到一个低频子带和若干个高频子带。(Under the image of non-sampling wavelet transform, to get a low-frequency sub-band and a number of high-frequency sub-band.)
