彩色多普勒成像分析，通过多普勒频谱进行彩色成像(Color Doppler)

basic lab circuit of halfwave coverter

通过matlab设计的GUI界面实现语音信号的实时录入和频谱分析和滤波等处理，并能够显示各阶段时域波形及频谱图，滤波器种类及参数可调(Through the GUI interface designed by matlab, the real-time input of speech signal, spectrum analysis and filtering are realized, and the time-domain waveforms and spectrograms of each stage can be displayed, and the types and parameters of filters can be adjusted.)

可以对任意实现频谱细化，函数的参数见函数自身说明(Spectrum can be achieved for any refinement, the function of the parameters see the description of the function itself)

说明：  全书分别从基础入门、程序设计、数值计算、符号运算、科学计算的可视化、图像处理功能、声音处理功能、底层文件输入输出操作、图形用户界面编程和应用程序接口方面进行介绍。(Respectively, from basic entry-book, programming, numerical computing, symbolic computation, scientific visualization, image processing, audio processing, the underlying file input and output operations, a graphical user interface and application programming interfaces introduced aspects.)

无监督聚类算法,能够自动聚类,不必预先给出类数,聚类精度好于常用的聚类算法.(Unsupervised clustering algorithm, can automatically cluster, do not have to give in advance the number of categories, clustering accuracy of better than commonly used clustering algorithm.)

This tool launches a GUI for thresholding an intensity input image. A line on the histogram indicates the current threshold level. A binary image is displayed in the top right based on the level, click and drag the line. The output image updates automatically.

本例演示：1、画两个同心圆，其中一个半径由独立输入宗量定义，另一个由变长度输入宗量的第一个元素定义，可以用任何指定的色彩线形绘制；2、变长度输入输出宗量在程序中的构成和使用；3、变长度输入输出宗量的对外使用表现(the cases demonstrated : a painting of two concentric circles, with a radius of independent input variables defined Another variable length from the importation of the first cases of an element of the definition, can be used in any linear color rendering; 2. Variable length input and output variables in the process of composition and use; 3, variable length input and output variables in the external use of performance)
