Matlab for speech coding encode

核主成份分析提取特征值的方法 还不错 可以试试(kernel pca for the value)

说明：  海量数据导入与导出matlab的有效方法，在数学建模时处理大量数据非常有用(Mass data import and export matlab effective method, in the mathematical modeling is very useful to deal with large amounts of data)

程序实现二次B样条平滑，三次B样条平滑；二次B样条平滑后节点插值(Program to achieve the second B-spline smoothing, cubic B-spline smoothed after the second B-spline interpolation smooth node)

其基本思想是：采用信号与噪声的状态空间模型，利用前一时刻地估计值和现时刻的观测值来更新对状态变量的估计，求出现时刻的估计值。它适合于实时处理和计算机运算。 (The basic idea is: use of signal and noise state-space model, the estimated value of the previous time and are always observations to update the estimated state variables, find an estimate of time there. It is suitable for real-time processing and computing.)

用于信道估计的LS算法仿真 我们对基于信道估计的训练序列进行了一个详细的研究，此种训练序列是用在中继节点的转接放大设计上。(we provide a complete study on the training based channel estimation issues for relay networks that employ the amplify-and-forward (AF) transmission scheme.)

这是一个用matlab编写的，基于CAMC，pid神经网络的非线性系统识别程序，能够很好的识别非线性系统(Based on CAMC/PID Nonlinear System Identification)

基于模拟退火的粒子群算法，具体问题可以参见十一届华为杯数学建模E题乘车物流规划问题前三问(This is simuAPSO,very good！)
