image swirl,input angle,fuction and output swirl

说明：  给大家上传一个关于matlab的数学建模实例，同是还有一些编程教程(For everyone to upload on the mathematical modeling matlab examples, the same there are some programming tutorials)

说明：  基于MATLAB的一个电力系统潮流分析程序，效果不错(A MATLAB-based power flow analysis program, good results)

此代码是基于matlab的代码，包含了图像金字塔，矩特征，边沿检测，斑点检测，角点检测，融合技术，图像去噪，车牌识别等等常用的一些图像处理技术！(This code is based on the matlab code, including the image of Pyramid, moment feature, edge detection, blob detection, fusion, corner detection, image denoising, license plate recognition and so on some commonly used image processing technology!)

四通道全息图的生成与重建代码，具有一定的借鉴意义(Code generation and four-channel hologram reconstruction, with some reference)

The model used for creating the reference voltage is shown in Fig. 4. First, photovoltaic output current (Ipv) and output voltage (Vpv) are passed through a first order low pass filter with a magnitude of G = 1 and a time constant of T = 0.01 seconds in order to filter out the high frequency components or harmonics from these signals as shown in Fig. 5 and Fig. 6. The filtered current and voltage signals (Ipv_F and Vpv_F) are then fed into the MPPT control block that uses the Incremental Conductance Tracking Algorithm. An algorithm that is based on the fact the slope of the PV array power curve shown in Fig. 7 is zero at the Maximum Power Point (MPP), positive on the left of the MPP, and negative on the right. The MPP can thus be tracked by comparing the instantaneous conductance (I/V) to the incremental conductance (∆ I/∆ V) [11] as in (1):

Three phase high frequency isolated DC-DC converter (published in ELSEVIER)is simulated under symmetrical open loop control. It provides Low voltage conversion ratio, isolation, good regulation with fast dynamic response.

Another advantage is that geometric properties of the curve are easily determined from a particular level set of the surface . For example, the normal vector for any point on the curve C is given by:

可以实现向量场的绘制，简单导入即可实现结果(vector field)

The purpose of this document is to give a medium-length introduction to the essentials of MATLAB and how to use it well. I’m aiming for a document that’s somewhere between a two- page introduction for a numerical methods course and the excellent but longer Getting Started and other user guides found in the online docs. I use it in a week-long “boot camp” for graduate students at the University of Delaware in the summer after their fi rst year of study.
