这是我自己写的对图像进行预处理的matlab源程序，主要是对图像进行光照补偿、旋转与尺度归一化。上传上来和大家一起学习、分享。(This is I wrote it myself pretreatment image matlab source, mainly for image illumination compensation, rotation and scale normalized. From up and study together, to share.)

this code is LSB data hiding source book.

全数字调制解调器MATLAB仿真真源代码，超级实用，下载即可使用。 (All-digital modem MATLAB simulation is really the source code, super-practical, can be used to download.)

采用前推回代法计算配电网潮流的程序，同时给出了IEEE33节点的算例(Using forward and backward substitution method to calculate distribution power flow program, and gives examples of nodes IEEE33)

fft计算相关函数，验证4096点的FFT快速捕获算法(理论仿真)(fft calculation of correlation function, verify the 4096-point FFT algorithm for fast capture (theoretical simulation))

matlab振动信号处理工具包可以进行滤波，信号时频域转换，试验模态参数辨识，时间序列分析等功能(MATLAB vibration signal processing tool bag, filter, experimental modal parameter identification and time series analysis and other functions)

说明：  多径多普勒信道模型，包括快衰落，慢衰落，频率选择性衰落，平坦衰落等(Multipath Doppler channel models include fast fading, slow fading, frequency-selective fading, flat fading, etc)

用matlab编写的软件，用于人脸检测的一个很好用的软件，可以自己随便找一幅图像进行测试。(Matlab software used to prepare for the face detection software used in a very good, can not find an image for testing.)

关于matlab的一些基本运算，一些调好的例子，包括加、减、乘、除。(Some basic operations on matlab, some adjustable good examples, including the addition, subtraction, multiplication, and division. )
