(1) margin function: Calculate amplitude margin and phase angle margin and corresponding turning frequency Margin (mag,phase,w): The amplitude of mag (not in db), phase angle phase, and angular frequency w vectors obtained by the bode instruction are plotted with a bode graph with headroom and corresponding frequency display. Margin (Num,den): Calculates the amplitude margin and phase angle margin of the continuous system transfer function representation and plots the corresponding baud plot. S

MATLAB Image Processing _ homomorphic filtering, matlab Image Processing homomorphic Homomorphic filtering: uses the generalized superposition principle to filter the homomorphic system. Homomorphic filtering is an image processing method that combines frequency filtering and grayscale transformation. It relies on the image illumination/reflectivity model as the basis for processing in the frequency domain,

Matlab reads 3D point cloud data Stanford rabbit, matlab Stanford Where the point cloud data is Stanford rabbit. After the 3D point cloud reconstruction, people can take a good look, but simply read the program. As a beginner, it is better, and further research is still behind, if you have the opportunity to continue uploading, for example, delauny triangle mesh division, you also want to further study the

When the threshold is th, the corresponding FRR has a value and far has a value. In this way, a group of corresponding FRR and far are obtained. The far is used as the horizontal coordinate, and the FRR is used as the vertical coordinate to draw the curve, that is, the ROC curve. Then draw the Y = x curve. When the two curves intersect, th

Mix C and matlab in Linux and mix linuxmatlab1 Overview 1.1 Introduction to Matlab MATLAB is a commercial mathematical software developed by MathWorks. It is used for algorithm development, data visualization, data analysis, and numerical computing. It is a high-level computing language and interactive environment. It consists of two parts:

Programming Method and Implementation of VC ++ and Matlab Interfaces AbstractThis article introduces the features of VC ++ and MATLAB, discusses three methods of programming the MATLAB and VC ++ interfaces, and discusses in detail the methods and implementation processes of programming the MCC and COM component interfaces. The research shows that using

Use of MATLAB Compiler (compiler) or MCC-- Personally think it is the right way 1. Set the Compiler: Http://www.cnblogs.com/fence/archive/2010/10/16/1853276.html First, you need to configure your own MATLAB compiler. The function of MATLAB compiler is to compile the program into a program that can be directly executed by the machine. To configure compiler, enter

In scientific research and engineering application, the algorithm often has to do a lot of mathematical calculation, including matrix operation. These operations are generally difficult to use manually accurate and fast, but the use of computer programming corresponding procedures to do approximate calculation. The current popular use of basic, FORTRAN and C language programming program, not only need to have a deep understanding of the algorithm, but also need to master the language used in the
