说明：  通过不同大小的窗口移动，计算每个窗口内地形剖面数据的均方根值，得到的数据在双对数图中拟合直线可求得分维数(move the windows of different size and calculate the rms of the data in the window.Then using the resultant data to plot,so that the fractal dimension can be gotten.)

说明：  to check the uniformity of generated random numbers using ks test

信号测量时，传感器优化布置的条件数方法。提供自由度信息，输出不同数量传感器的最优布置方案。(signal measurement, the sensor layout optimization of several methods. Provide freedom of information, the number of different sensor output optimal layout of the program.)

matlab求解非线性方程M-文件，用于计算机快速求解方程(matlab solving nonlinear equations of M-files for computer quickly solve the equations)

利用kalman滤波器对具有随机加速度的物体运动路线的进行信号采样，滤波处理和估计。(use kalman filter to sample signals of object moving route with random acceleration,filter and estimate)

insertion of two images iand how to exctract them

基于传递矩阵的方法，计算转子动力学系统临界转速及振型(Critical Speed and Vibration Mode of Rotor Dynamics System Based on Transfer Matrix Method)

本程序设计的是咬尾编码的turbo码，用matlab编写。咬尾turbo码也即不需要拖尾比特，使得前后两个状态相同，译码采用修正的MAP译码算法,此为咬尾turbo编码算法(This program is designed to encode the turbo tail biting code, written with matlab. Tail biting turbo code that is not trailing bits to make the same before and after the two states, the MAP decoding using modified decoding algorithm, this is the tail biting turbo coding algorithm)

从最常用的“.BMP”图像格式中读取图像数据, 通过访问数字图像RGB三个通道的对应矩阵，改变数字图像的色彩 将数字图像的RGB表示转换为YUV表示；通过访问Y（亮度）通道，改变数字图像的亮度；通过Y（亮度）通道作灰度的线性变换，改变数字图像的对比度(failed to translate)

该程序用CZT算法实现信号频率分析，并画出信号的波形图、FFT变换后的频谱图、CZT变换后的波形图(CZT transformer )
