图像的图特征算法和代码，含有处理图片和处理后的结果(image feature matlab code)

matlab下m文件，能够提取compass三轴原始数据，并自动进行拟合矫正，得到其变换矩阵。将椭圆自动校正为圆心在原点的正圆。专门用于磁力计和重力计的自动校正。(m file matlab compass can be extracted under triaxial raw data and automatically correct fitting to give its transformation matrix. The ellipse is automatically corrected to a perfect circle centered at the origin. Specifically for magnetometer and gravity meter automatically corrected.)

判断参数的影响因素，本人已亲测，请大家放心下载(Judging the influence of parameters)

MATLAB程序设计教程的源码，对初学者很有帮助，欢迎下载(MATLAB programming tutorial source code, useful for beginners are welcome to download)

SHA-1 Source Code This optimized SHA-1 implementation conforms to FIPS 180-1

说明：  处理波形，计算声波再通过障碍物以后的延迟,从而计算声波在不同介质中的传播速度(Treatment of waveform, calculated the time delay after the sound waves pass through the obstaclesand，In order to estimate the acoustic propagation velocity in different media)

在数字图像处理中，运用MATLAB中的函数compare可以用来计算图像压缩前后的误差和直方图(In digital image processing using MATLAB functions compare the error and histogram can be used to calculate the image before and after compression)

说明：  AR一阶算法，可利用AR（1）进行数据预测和随机序列处理(AR First Order Algorithms)

this is a matlab program which generates OFDM signals
