说明：  matlab入门，比较适合于初学者，有兴趣的可以参考下。(the introduction of matlab)

说明：  cootes提出的ASM算法的matlab实现。在cootes用于课堂使用的源代码的基础上改写。改正了原来代码中的一些错误，加入了方便使用的样本训练标注保存环节。供图像分析处理，模式识别，人工智能研究者使用。(the ASM Algorithm Implementation of Matlab. Cootes used in the classroom use of the source code on the basis rewritten. To correct the original source of some mistakes, joined the ease of use of training samples preserved tagging links. For image processing, pattern recognition, artificial intelligence researchers.)

选择13级移位寄存器的初始数据，用移位加反馈的方法生成级数为3~13的m序列(The selection of the initial data of 13 level shift register, series is generated by shift plus feedback method for 3 ~ 13 m sequence )

可以对某一块海洋区域进行纵切断面，并在一张图上生成几个图片(Can conduct a longitudinal section of a marine areas, and generate a few pictures on a map)

this code in used in neural network mlp with back propagation training algorithm and geradian descends algorithm for optimization.in some of this codes I used full propagation algorithm or mlp one layer or two layer with different activation function.this code can be use for prediction or control system by useing neural networks.

说明：  matlab科学计算继续上传，一共10个章节，由浅入深，几乎包括了绝大部分的科学计算方法以及仿真。本人把部分算法做了优化，更为完善(matlab scientific computing continue to upload, a total 10 chapters, easy-to-digest, almost, including most of the scientific method of calculation and simulation. I have done a part of algorithm optimization, a more perfect)

一种下垂控制的模型，参数设好，可以运行，仅供参考学习。( One kind of droop control model, the parameters had set up, you can run it,just for reference study.)
