Rayleigh-in-Transmit-beamforming

基于偏微分方程的多级分层的图像增强算法，(Multi-level hierarchical image enhancement algorithm based PDE algorithm)

fft分析与恢复,基本的matlab入门程序，初学者适用(fft analysis)

用于对非线性方程的参数估计和最优估计的粒子滤波算法，保管一看就会，步骤很清晰的。(the solution of non-line function by pf filter)

以MATLAB將影像做色彩空間轉換， 轉換的色彩分別為RGB轉Gray scale, RGB轉YUV, RGB轉lab, RGB轉HSV(MATLAB will do to the image color space conversion, the conversion of RGB colors were transferred Gray scale, RGB turn YUV, RGB turn lab, RGB and HSV)

根据多行三列的实验数据（x,y,signal)作出contourf图。其中x,y为二位空间位置（或其他概念的二维），signal为在该位置的信号。此代码先将数据按位置不同求平均，再将signal按照其对应的x,y分配到二位矩阵内。最后作图。编这个代码的初衷是为了制作大脑hippocampus区域place cell 活动性的contour 图。(it s a code i made for plotting a contour graph of experimental data (x,y,signal). The data should be n*3 arrays which cannot be plot into contour directly. In fact, it can subplot 6*6 graphs or more, but speed might be slow..... especially, when you want more detailed graphs.)

OPENCART V1.56 中文使用说明书，主是要讲怎么配置商城。(OPENCART V1.56 Chinese instructions for use, the main is to tell how to configure the mall.)

当我完成了我的运动检测里卖软饮料在matlab和更新代码,后来我改变了对C实现过程对DSP板。这是一份报告,对DSP板工作但是你可以发现这背后的概念。 (As I Initally performed my motion detection on matlab and updated the code, later I shifted the process on C to implement on DSP board. This is a report that works on DSP board but you can find the concept behind this.)

An alternative to Matlab s HIST, function HISTW prevents extreme values in top and bottom percentiles of an input vector affecting the histogram s scaling, obscuring location and shape of the distribution s main mass. Limits of x and y (maximum only) axes can be set, and a marker line drawn at given x position. In contrast to HIST, bin size can be explicitly specified, and relative, rather than absolute, frequencies are plotted.

Aiming at determining the satellite attitude precisely，the gyros bias and m isa lignment were compensated in time by using the quaternion of star-sensor and extended Kalm an filter．The related module of the filter was derived．The theoretic accuracy of the algorithm was acquired from the numerical simulation． The effects of the star-senso r misalignment on attitude determination were analyzed at last．
