求矩阵的逆阵，利用高斯消去法，是本人编写的MATLAB源码(Inverse matrix array, the use of Gaussian elimination is, I prepared MATLAB source)

This MATLAB code computes the covariance matrix of a random variable

：滤波 fs=400 采样频率,必须大于两倍基带信号最高频率 ts=1/fs 采样时间间隔 T=5 时间窗大小 t=0:ts:T (hf1=zeros(1,N) hf1(f<=B1&f>=-B1)=1 y1=hf1.*fftshift(y) figure subplot(211) plot(f,abs(fftshift(y))/N,f,hf1, r-- ) axis([-fs/2,fs/2,0,1.2]) title( 原信号频谱 ) xlabel( f /Hz ) subplot(212) plot(f,abs(y1)/N) title( 低通滤波，截止频率90Hz ) xlabel( f /Hz ))

基于MATLAB的程序编码。实现一种编码方式，实现对信号的内插级抽取(MATLAB-based program code. Implement a coding scheme to achieve the interpolation level signal extraction)

黄变换的代码，经验模式分解，可用于信号分解(Huang transform the code, empirical mode decomposition can be used for signal decomposition)

随即序列的MATLAB pcm编译码实现，方便同学理解，简单易懂 (Sequence of MATLAB pcm codec then implemented to facilitate students to understand, easy to understand)
