贝塞尔曲线拟合程序，完全利用matlab实现(Bezier curve fitting procedures)

说明：  matlab在通信工程的应用以及matlab在曲线拟合和函数图像的应用(matlab works in communications applications, as well as matlab curve fitting and function in the application of image)

回波信号模拟，北京航空航天大学的关于雷达的教材里拷的(Analog echo signals, Beijing University of Aeronautics and Astronautics on the radar copy materials in the)

换能器阵元的不同排列组合决定其指向性，波束形成是多波束测量的关键技术。文中 通过数学计算总结了不同换能器阵进行波束形成的工作原理，并介绍了利用二维DFT进行频 域波束形成的一般方法。最后结合现役多波束测深系统，简单解释说明不同系统所采用的波束 形成技术。(Transducer using an array of different permutations and combinations to determine its directivity, beam formation is the key technology for multi-beam measurements. Summarized by mathematical calculations the transducer array beamforming works, and describes the general method of two-dimensional DFT in the frequency domain beam formation. Finally, the active-duty multi-beam sounding system, the simple explanation of the different systems used in beamforming technology.)

the Matlab project contains the source code used for simple watermarking using wavelet transform. Performs watermarking of the input image by decomposing the image using haar wavlet. Noise generated with normal distribution is used as the key and is added to the input image to obtain the watermarked image.

PO ALGORITHM SIMULATION

很长的一个例子，说实话，我也看不懂。。这个是同学写的。(An example of a very long, I can honestly say I do not watch. . This is the Student Writing.)

matlab 画viviani曲线+绘制分子结构+最小二乘拟合+求信号包络线+滤波器设计（一次为大家提供5个matlab完整程序，能调试准确的结果仿真图）(matlab draw viviani curve++ least-squares fit to draw the molecular structure of++ request signal envelope filter design)

simulink滤波率仿真 二阶和四阶低通滤波(filtering rate simulation simulink second and fourth-order low-pass filter)

说明：  运用相移延拓的方法有效地模拟地震波在介质中的传播路径。(Extension of the use of the phase shift method can effectively simulate seismic wave propagation path in the medium.)
