对测量专业中不同时期观测的数据进行精度是否相同进行统计检验(The measurement data of observation in different periods in the professional statistical test accuracy are the same )

此压缩文件是对gardner算法利用插值滤波实现定时恢复的matlab仿真。包含了三个文件，一个word文档，对程序作了详尽说明；另一个m文件(Timing_Recovery)

动态时间规整程序,Matlab编写,用于两个序列的对齐(Dynamic time warping process, Matlab to prepare for the alignment of two sequences)

文献“Sparse Representation based Fisher Discrimination Dictionary”及其对应的matlab代码，稀疏学习是目前非常流行的方法，希望对大家有所帮助(a paper named Sparse Representation based Fisher Discrimination Dictionary and its matlab code)

第k小元素（分治法） 给定一个线性序列集，要求求出其中指定的第K小的数的值和位置.如给定n个元素和一个整数i，1≤i≤n，输出这n个元素中第i小元素的值及其位置；(First k small element (divide and conquer) Given a set of linear sequence, where the specified requirements determined the K value and the small number of locations, such as a given n elements and an integer i, 1 ≤ i ≤ n, output this is the n elements of the i-th element value and the position of the small )

一本关于龚纯编辑的数学建模MATLAB应用的书，很实用的，不过不是很清晰(Gong edited a book on mathematical modeling of pure MATLAB application book, very practical, but not very clear)
