用MATLAB计算Thue-Morse超晶格的光透射率(Calculated using MATLAB Thue-Morse superlattice light transmittance)

说明：  给定一幅图片输出其直方图，灰度拉伸，均衡化后的灰度直方图(Histogram, gray stretch, equalization)

contrast enhancement on grayscale image based on Posibility Distribution

说明：  QPSK仿真OQPSK仿真，通信原理资料上面的 (QPSK)

说明：  一些数字信号处理的matlab函数实例，相信对大家会有点帮助(Some digital signal processing function of the matlab example, believe that you will help a bit)

用matlab程序生成四分体马赛克图片，付图片以供试验(create mosaic picture)

The Scale-Invariant Feature Transform (SIFT) bundles a feature detector and a feature descriptor. The detector extracts from an image a number of frames (attributed regions) in a way which is consistent with (some) variations of the illumination, viewpoint and other viewing conditions. The descriptor associates to the regions a signature which identifies their appearance compactly and robustly

信源产生、信道编码、调制、信道传输、解调、信道译码、差错比较等通信过程的Simulink仿真方法。分析QPSK调制方式下Hamming编码方式在不同信噪比下的通信质量。 (Generated source, channel coding, modulation, channel transmission, demodulation, channel decoding, error comparison of the communication process of the Simulink simulation. QPSK modulation mode of Hamming encoding different signal to noise ratio in the quality of communication.)

艾肯特插值，高斯插值和牛顿插值法的matlab代码。上述三种方法均用于数值插值。(Ai Kente interpolation, the matlab code of the the Gaussian interpolation and the Newton interpolation law. The the above-mentioned three methods are used for the numerical interpolation.)

系统辨识作业，仿真比较OE模型 ARMAX模型 和ARX模型的便是效果，内涵ppt。(System identification operation, the simulation model compared OE and ARX model ARMAX model is the effect, meaning ppt.)
