本matlab程序对滚动轴承的外圈进行了分析研究，与正常情况下的做对比，可以发现故障的位置，进一步的对比还要再做研究。(The matlab program analysis, and under normal circumstances, the contrast of rolling bearing outer ring, you can find the location of the fault, further comparison should also do research.)

包含飞行器飞行中的姿态控制，如侧滑角，倾斜角，滚转角，俯仰角，主要为数据分析和统计，光纤陀螺输出误差的allan方差分析。( It comprises aircraft flight attitude control, such as slip angle, tilt angle, roll angle, pitch angle, Mainly for data analysis and statistics, allan FOG output error variance analysis.)

half wave rectifier one of the best

产生雷达巴克码（Barker）信号，码内线性调频（LPM）。 RD_wave_mix.m 产生Baker码信号函数 test_wave_mix 测试函数(The Barker code (Baker code) radar signal, linear frequency modulation (LPM). RD_wave_mix.m Baker generated code signal function test_wave_mix test function)

Simple code for clipping

实现正弦波生成的matlab程序，基于矩阵公式推导，可以延伸变化(Sine wave generated by the realization of matlab program, based on the matrix formula is derived, the changes can be extended)

内共有两个程序：1.用Mallat算法实现一维小波变换；2.用DWT实现二维小波变换。 从仿真图可以加深对小波概念及小波变换的原理。(A total of two procedures: 1. Mallat algorithm using one-dimensional wavelet transform 2. With the realization of two-dimensional wavelet transform DWT. From the simulation wavelet map can deepen their understanding of the concept and the principle of wavelet transform.)

this is a code to calculate the moment invariant of images. the values which come out are capable of removing rotational, scaling, transnational variation in image given as input.classification can be done with the help of it.

使用小波技术对图像进行压缩和解压过程，并且通过模拟信道测试计算其PSNR，通过Matlab2009a测试。(Using wavelet methods compress and decompress the image, and testing through analog channels to calculate the PSNR, by Matlab2009a test.)

说明：  MATLAB中画椭圆的自定义函数：ellipse，用后才会发现这个函数的强大功能！ 在ellipse之函数当中，其输入之变数分别如下： -ra 椭圆之长轴半径，可为列矩阵，若为列矩阵时，代表可同时绘制许多椭圆。 -rb 椭圆之矩轴半径，可为列矩阵，如ra。 -ang 水平轴之倾斜角，以弧度表示。可为列矩阵，但ra、rb、ang三者之矩阵数应相同。 -x0,y0 圆心之座标，可为矩阵，若为矩阵时，代表可同时绘制许多不同圆心位置之椭圆。 -C 椭圆线之颜色 -Nb 绘椭圆时所用之点数。(MATLAB in the oval painting custom function: ellipse, will be found after using the power of this function! Ellipse of the function in which its input variables are as follows:-ra ellipse of major axis radius for the column matrix, if for the column matrix, a representative may at the same time drawing many elliptical. oval-rb-axis radius of the moment for column matrices, such as ra.-ang horizontal axis of the tilt angle to radians. Matrix for the column, but ra, rb, ang among several of the matrix should be the same.-x0, y0 the coordinates of the center for the matrix, if for the matrix, a representative may at the same time drawing a number of different oval center location.-C elliptic line color-Nb painted oval of points used.)
