distribution

可以进行直方图计算，也可以进行灰度运算，可以实现图像的变换操作(Histogram can be calculated, it can be gray-scale operation, the image transformation operation can be achieved)

层次分析法的程序代码，不错的一段代码，希望能喜欢(AHP program code, a good piece of code, hoping to enjoy)

Digital Bandpass Transmission(Digital Transmission)

说明：  1.相关分析法辨识系统程序。2.方波响应与阶跃响应的互相转化的通用程序。3.获取系统模型阶次的函数。4.levy方法辨识系统的函数。5.将相关分析法的辨识结果转成频率响应的程序((1) analysis Identification System program. 2 square wave response and step response of the general program of mutual transformation. (3) for the function of the system model order. 4.levy method recognize the function of the system. The identification of the relevant analysis results converted to the frequency response of the program)

超宽带基础的基本程序,非常不错的小程序,省不少事情啊(the basic procedures, a very good small procedures, many of the things the provincial ah)

基于数字地球的车载卫星导航定位的设计与实现(Digital Earth s satellite navigation and positioning the vehicle design and implementation)

短时傅里叶变换可以用差分模式来实现，对书上的运算式做了稍许的改变。改变-计算差分序列的第一列数据时用的是第一列的元素减去当前行的最后一列元素。原算法中采用的是第一列元素减去下一行第二列元素。原算法加窗之后结果比较好，不加窗时结果误差很大，而改变之后的算法不加窗效果依然很好。(Short time Fourier transform can be used to achieve the differential mode of expression on the book made a slight change. Change- calculating the difference sequence of the data with the first column is the first column of the matrix by subtracting the current element in the last column of row. Is used in the original algorithm subtracts the elements of the first column of the next row and the second column elements. After the results of the original algorithm windowed better, when the results window without great error, and after changing algorithms no window effect is still very good.)

filter，本代码主要介绍filter的主要步骤，非常简单有很明了，非常适合阅读(Filter, the code describes the main steps of filter are very clear, very simple, very suitable for reading)

this code described by Matlab file for fitting process for the extract a ellipse curve from the 2D noisy ellipse image.
