研一上学期，学校开了数值分析这门课，而且要求用matlab进行上机试验，经过一段时间的学习，对matlab有了最初步的了解，结合所学课程，废了好大的劲才编了几个小程序，希望对后来学习的人有点帮助。(Kenichi last semester, the school opened the numerical analysis of the course, but also carried out on machines with matlab test, after a period of learning, of matlab with the most basic understanding, combined with the course, the repeal of several large series劲才a few small programs, and they hope to learn a little bit later to help.)

Abstract - In this paper, proposed an efficient method of converting speech codec formats between G.723.1 and G.729А. The proposed method is composed of four steps: LSP conversion, pitch conversion, adaptive codebook search and fixed codebook search. Subjective results shown that the proposed method has shorter delay than classical tandem method.

说明：  基于lms的自适应均衡器 作用很大效果很好(lms)

说明：  《模糊逻辑》（Fuzzy Logic）一书的例子程序，作者： Reza Langari("fuzzy logic" (Fuzzy Logic), an example of the procedure, the authors : Reza including)

用matalb实现QuartusII中的初始化文件（.mif或是.hex)文件，涉及到matlab中文件的读写步骤。(Realize the initial files(.mif or .hex) using matlab,and it involves writing and reading in matlab. )

说明：  matlab应用于神经网络：数字卡片0~9奇偶识别(matlab neural network applications: Digital Card 0 ~ 9 parity Recognition)

matlab的pso工具箱 很好用 直接不用编程序了 只需要修改一下函数就可以(The good toolbox matlab pso not directly programmed with the only change it can function)

偏微分方程的MATLAB解法 对学习matlab环境下计算偏微分方程有很好的帮助。同时，也可以用其中的PDEOOL为计算流体力学中的二维问题生成三角形网格，减少前处理工作量(Solution of Partial Differential Equations MATLAB computing environment for learning matlab partial differential equations have a good help. Also, you can use one of the PDEOOL for the two-dimensional computational fluid dynamics problems in the triangular mesh generated, reduce the workload of pre-treatment)

说明：  实现大容量的图像信息隐藏，采用双随机置乱算法(Realize large-capacity image information hiding, using double-random scrambling algorithm)

Matlab常用信号产生函数演示实例：编写一个M文件，依次产生均匀分布的随机序列、高斯白噪声随机序列、方波信号序列、三角波信号序列、正弦波信号序列，以及信噪比SNR为10dB的加性高斯白噪声正弦信号。(Matlab commonly used signal generating function demo examples: write a M file, in turn generating uniformly distributed random sequences, Gauss white noise sequence, square wave signal, triangle wave signal sequence, sine wave signal sequence, as well as for the 10dB than the SNR signal-to-noise additive Gauss white noise sine signal.)
