画poincaremap and bifurcation 图(Draw images of various differential equations and poincaremap image, bifurcation images, gui form)

matlab简介，对初学者来说是一份很好的学习资料(Matlab Introduction, is a very good learning materials for beginners)

巴特沃斯陷波滤波器的程序 保证可用 直接运行即可 注意：matlaB目录设置要一致哈(Butterworth notch filter can be used to ensure the program can be run directly Note: matlaB directory is set to be consistent )

该代码实现了以2为因子的图像升采样和降采样功能。 降采样包括使用平滑滤波器(with using the averaging filter)和不使用平滑滤波器(without using the averaging filter)两种方法。 升采样包括像素点直接复制(pixel replication method)和线性插值(bilinear interpolatoin method)两种方法。 降采样方法和升采样方法共有4种组合。程序运行后，给出了一个原始图片和四个结果图片。 图片1.原始图片。 图片2.平滑滤波器降采样&像素点直接复制升采样。 图片3.平滑滤波器降采样&线性插值升采样。 图片4.不使用平滑滤波器降采样&像素点直接复制升采样。 图片5.不使用平滑滤波器降采样&线性插值升采样。 (The code to achieve a 2-factor image upsampling and downsampling function. Down-sampling (with using the averaging filter) and do not use smoothing filter (without using the averaging filter) are two ways to use the smoothing filter. Upsampling including the pixels copied directly (pixel replication method) and linear interpolation (bilinear interpolatoin method) two methods. Down-sampling method and liters a total of four combinations of sampling methods. The program is running, it shows a picture of an original picture and four results. Picture 1 original picture. Photo 2. Smoothing filter downsampling & the pixel directly copied liter sample. Photo 3. Smoothing filter downsampling & the linear interpolation liter sampling. Picture 4. Smoothing filter down-sampling & the pixels directly copied liter sampling. Picture 5. Use smoothing filter down-sampling & the linear interpolation liter sampling.)

贝塞尔曲线拟合程序，完全利用matlab实现(Bezier curve fitting procedures)

this is the most common type of fading model observing in urban cities

是matlab代码 有关非线性最小二乘问题的非常有用，希望给大家帮助(matlab code about nonlinear least squares problems it is very useful )

matlab波速成形，讲解波束成形的过程，以及形成的方法(and matlab is wave velocity molding, explain the beamforming process and the method of forming)

matlab 源码 实现宽带通信中多入多出系统性能的最优化(matlab original code implement wimax system perform optical)
