matlab的GUI开发，对于matlab学习非常有用！(GUI development of matlab)

这个程序用来说明单频离散序列的周期延拓和补零延拓会对频域的分辨率有什么影响，是我自己刚作出来的，就贡献了吧，请您审查通过(the procedure used to describe single-frequency cycle sequence of discrete Extension and Extension-zero frequency domain will have a resolution of any impact option is my own just to make the contribution on the right, please review by Thank you)

Tests the switch statement.

This is a project for Gas agency System.You can check the doc and sourcecode

说明：  进行Gray码的图像变化，思想是进行位操作，首先将原始图先的每一位取出来， 然后将十进制转化位二进制，将其按位取出，进行变换，得到变换后图像的每一位的值，再进行组合即可(Gray code for the image change idea is to place operation, first the original plan to take out each and every first and then bit binary decimal conversion, be removed by bit, for transformation, transformed the image of each of value, then the combination can be)

运用MATLAB对波形的进行最优预处理，处理以后的曲线的效果非常好 使用的时候，把TXT里面的程序复制到在MATLAB里面新建立的.MAT文件中，按F6运行(use of MATLAB waveform for the optimal pretreatment, After dealing with the effects of the curve very good use of time TXT put inside the copy of the MATLAB inside the new building. MAT document, the operation by F6)

压缩文件中给出了已知系统传递函数及输入信号的情况下，求解系统输出响应的四种方法，即差分方程法，卷积法，DFT法以及滤波器设计方法；此外还包含创建窗及其频率响应的matlab设计。(Known compressed file system transfer function is given and the case of the input signal, the output response of the system to solve the four methods, namely the differential equation method, convolution, DFT method and the filter design methods Also included creating windows and its frequency response matlab design.)

基于人工神经网络的常用数字信号调制，包括脚本文件和函数文件形式，窗函数法设计一个数字带通FIR滤波器。( The commonly used digital signal modulation based on artificial neural network, Including script files and function files in the form, A window function design FIR digital band-pass filter.)
