说明：  matlab中一些重要的课件和资料，比较有用啊！(matlab courseware and some important information, more useful ah!)

this code reduce the dimentional of feature space using combine sparse matrix+PCA for classification eeg signal. more detail exixst inside the code. this code tested and work properly

LM滤波器组程序，用于图像纹理提取和处理，共有48个滤波器组成，在图像处理中应用(LM filter banks in matlab )

OFDM的matlab仿真源程序，非常详细。(Matlab simulation of OFDM-source, very detailed.)

讲小波包中尺度函数系数的计算，对于小波滤波器的设计比较实用(Mesoscale speak wavelet packet coefficients calculations, more practical)

验证可用，采用偏最小二乘法，包括最后计算压缩图像的峰值信噪比和压缩效果的源码。( Verification is available, Partial least squares method, Including the final calculation of the compressed image peak signal to noise ratio and compression of the source.)

1.n个节点分段Lagrange插值多项式； 2.使用格式y=lagrange(x0,y0,x,k)； 3.输入项x0为n维插值节点向量，y0为n维被插函数值向量； 4.x为m维插值点向量，k为分段插值多项式次数，不超过3，缺省为k=1； 5.输出y为插值点x处的函数值；( 1.n a sub-node Lagrange interpolation polynomial 2. The use of the format y = lagrange (x0, y0, x, k) 3. Input x0 of interpolation nodes for the n-dimensional vector, y0 for n-dimensional vector function to be inserted 4.x interpolation points for the m-dimensional vector, k is the number of sub-polynomial interpolation, not more than 3, the default for k = 1 5. output y for the interpolation points x Department of function )

用matlab编程来实现，用HMM模型进行孤立词的语音识别(using Matlab programming to achieve with HMM term isolation of Speech Recognition)

说明：  差别算法matlab代码（differential algorithm）及粒子群算法的介绍(difference algorithm Matlab code (differential algorithm) and the PSO algorithm introduced)

说明：  使用matlabR2008a编写的多元逐步回归模型 经过调试(Prepared using matlabR2008a After debugging multiple regression model)
