3-D FDTD code with PML absorbing boundary conditions(err)

再matlab下面实现信号的fft变换。 是fft函数。(fft)

Face Recognition using wavelet transform in matlab

基于纹理特征的图像检索源码，通过双树复小波进行纹理特征提取(Texture-based image retrieval source, through the dual tree complex wavelet texture feature extraction)

带通滤波，对输入的数据进行带通滤波，采样频率为实际频率的16倍，里面有关于矩阵和数据变换的程序，大家可以自己转换(Band-pass filter, the data input bandpass filter, the sampling frequency is 16 times the actual frequency, which on the matrix and data transformation process, we can convert their own)

this paper desctibes one of new method in photovoltaic issues. nice information included

texture and remote classification by using ANN

利用matlab对图像进行读入与处理（运用在仿真领域）(Use matlab to read the image and processing (used in the field of simulation))

第七章 IIR滤波器设计 数字滤波器：将输入序列通过一定运算，变换成输出序列的离散时间系统（数字网络）。 (Chapter 7 IIR filter design digital filters: input sequence is converted into the output sequence of discrete time system (Digital Network) through certain operations.)

信号的稀疏表示就是将信号投影到正交变换基(Sparse representation of the signal is a signal to the orthogonal projection transform base)
