OMP算法在压缩传感中的应用，这是一个m文件。(Orthogonal Matching Pursuit Algorithm for Compressive Sensing)

Halftones an input gray level image using using Fixed Thresholding, Random Noise Thresholding, Ordered Dithering, Floyd and Steinburg and Stucki Methods.

传输速率与码元宽度关系的matlab程序(Transmission rate and the width of the relationship between code element in matlab)

轮轨冲击信号的小波分析matlab程序,程序中H5V20zrail为轮轨冲击信号输入数据。(Wheel-rail impact of wavelet analysis matlab program, the program H5V20zrail impact signal for the wheel-rail input data.)

说明：  DBSCAN聚类算法，初步实现，功能比较简单，数据集比较简单(DBSCAN clustering algorithm, preliminary implementation, relatively simple function, relatively simple data set)

说明：  这是一个用matlab读取txt（特定格式）文件并读取文件，画出figure，自动保存和关闭figure。程序运用了深度搜索递归算法。（因为大家没有input的txt文件，所以阅读程序领会思想和方法即可）(This is a use matlab to read txt (a specific format) file and read documents, painted figure, on and off automatically to preserve figure. Procedures for the use of recursive depth search algorithm. (Because there are no input of the txt file, so reader can understand the ideas and methods))
