Detect circles with various radii in grayscale image via Hough Transform

内含五个程序 1.zoeppritz Aki K I 和Richards P G的纵波近似程序 2.地震记录合成程序 3.大地电磁一维正演程序 4.雷克子波合成程序 5.地震反射系数生成程序(1.zoeppritz Aki KI and Richards PG longitudinal wave approximation procedures 2. Seismogram synthesis program 3. Magnetotelluric one-dimensional forward modeling program 4. Ricker wave synthesis procedure 5. Seismic reflection coefficient generator)

This contains the full set of source files for the MatClass library together with a make file to create the libraries using Microsoft C/C++ v7 or later. This make file is a stand-alone file to be used with NMAKE or as a NON-PWB makefile in PWB. Note the make file generates uses the Large Memory model. It generates a library file called LIBMAT.LIB.

采用四参数生成法自动生成多孔介质(二维)，优化了出现独立单个节点、实体内部出现孔洞的问题(Four-parameter generation method automatically generates a porous medium, optimize the emergence of an independent single node, hole problems arise internal entities(2D))

信号分析与处理中的卷积，适用于合成地震记录(Signal analysis and processing of convolution, for synthetic seismograms)

说明：  给定n种物品和一个背包,物品i的重量是Wi,价值是vi,被包容量是C,应该如何选择装入被包的物品,使得装入背包中物品的总价值最大?对于每种物品i,只有两种选择,装入或者不装入. 输入:第一行两个正整数n(物品数)和C(容量) 第二行n个正整数n,表示物品价值 第三行n个正整数n,表示物品重量 输出:第一行表示总价值 第二行n个数(0/1),0表示物品不装入,1表示装入 例如, 输入: 5 10 6 3 5 4 6 2 2 6 5 4 输出 15 1 1 0 0 1 (Species of a given n items and a backpack, the weight of item i is Wi, the value of vi, was packet capacity is C, should be how to choose a package of items to be loaded, the backpack load in the largest total value of goods? For each item i, there are only two options, loaded or not loaded. Input: the first line of the two positive integer n (the number of items) and C (capacity) of the second line of n positive integer n, that the value of the third line of n positive integer n, that the weight of output: the total value of the first line of the second line, said n number of (0/1), 0 that the items do not load, that load 1 for example, enter: 5,106,354,622 6 5 4 output 15 1 1 0 0 1)

matlab编写的一个递归应用，同时生成动态链接库（dll）。并用vc++测试(matlab generate dynamic link library (dll). And using vc++ test)

用C++实现了MATLAB中fftshift及triang函数功能，代码是实现此二功能的函数(With C++ Achieved in MATLAB function fftshift and triang function code is to achieve a function of these two functions)
