在Juan Cardelino发布的FMM(fast marching methos)2维程序基础上改写的3维程序。并改写成适合复杂速度模型，可用于地震旅行时计算。大模型3d算法在matlab下计算速度较慢，根据源码中的注释很容易改写成c程序。(3D FMM program revised from Juan Cardelino s 2D version. The program can calculate the seismic traveltimes in 3D complex model)

3GPP标准Turbo码编码译码仿真Matlab6.5及VC6.0源代码，并包含Turbo码编码译码原理的介绍文档。(3GPP standard Turbo coding and decoding simulation VC6.0 Matalab 6.5 source code , and includes Turbo Encoder Decoder description of the principle of documentation.)

模式识别线性判别的程序实现，产生两个二维正态分布随机样本，分别进行Fisher线性分类和感知器分类。其中main.m是主函数，将三个程序放在同一文件夹中，运行main.m即可得到分类结果。(Pattern recognition linear discriminant program implementation, generate two-dimensional normal random sample, were Fisher linear classifier and Perceptron classification. Main.m is the main function of which will be three programs in the same folder, run main.m classification results can be obtained.)

对Matlab中的文件进行了解释和说明，对Matlab初学者有一定帮助(Matlab files for an explanation and description of the Matlab help beginners have a certain)
