说明：  用S函数编写的量化器 量化步长为非线性 即 量化步长可调 (Prepared by S function to quantify the quantizer step size for the non-linear quantization step size that is adjustable)

拥有很多有实际应用价值的MATLAB源程序代码(Has many practical applications of MATLAB source code)

自己编写的MATLAB函数，实现对图像的旋转。B是原图像，灰度或彩色，alpha是旋转角度（角度或弧度单位均可），A是旋转后图像。旋转后图像信息尽可能不损失。(I have written MATLAB function, to achieve image rotation. B is the original image, grayscale or color, alpha is the angle of rotation (degrees or radians per unit), A is rotated images. Rotation after the image information as possible without loss.)

Function H for Method upwind, Lax_Friedrichs and Lax_Wendroff for equation of advection 1d in Matlab

该程序实现了高斯白噪声环境下直流电平的检测.画出了似然比门限,虚警,漏警随先验概率,代价因自等变化的情况.(The program to achieve the detection of DC level Gauss white noise environment. Draw the likelihood ratio threshold, the false alarm, alarm with the prior probability, cost because of the changes.)

该程序和文档研究了在单径瑞利信道中，BPSK的误码率性能，画出比特信噪比与误码率的关系曲线，具体公式在文档中给出。(The study of the relationship between programs and documents in a single path Rayleigh channel curve, the BER performance of BPSK, draw the bit error rate and signal to noise ratio, the specific formula is given in the document.)

Stretches contrast on the image and normalize image from 0 to 1. The main difference of this function to the standard stretching functions is that standard function finds global minimum and maximum on the image, then uses some low and high threshold values to normalize image (values below LowTHR are equated to LowTHR and values above HighTHR are equated to HighTHR)
