laplacian边缘检 图象进行降噪处理 高斯滤波处理(laplacian edge detection image processing Gaussian filter processing for noise reduction)

利用MATLAB中的GUI（图形用户界面），实现图像的频率位移变换、加入高斯噪声、图像平滑、离散余弦变换、图像反转，并设计了退出按钮(In MATLAB GUI (graphical user interface), to achieve the image displacement transducer frequency, adding Gaussian noise, image smoothing, discrete cosine transform, image reversal, and designed the Exit button.)

knn算法，用的数据时iris数据，可以运行，所以放心使用(this is perfect)

利用Matlab求二维离散系统的分岔图程序。 在非线性动力学及复杂经济学中经常用到类似的问题。也可以用来画其他更高维数的离散映射系统的分岔图。很实用。(using Matlab for discrete two-dimensional map of bifurcation process. In nonlinear dynamics and complex economics frequently used similar problems. Can also be used for other higher-dimensional painting of a few discrete mapping system bifurcation plan. Practical.)
