recently debugging a MATLAB-based program, in the occasional found a few more interesting tricks, to share with you ( probably is too rookie, did not involve this aspect, the generous house does not have the laughed at, has the help to you to please likes! )1. Matlab language is an interpreted language (interpreter)as I summarize the software architecture Data flow:interpreter/virtual Machine (Interpreter/
Recently in the Exercise Medicine Software optimization work, this software framework and algorithm language is fully implemented by MATLAB, although the MATLAB matrix operations, numerical computing ability is powerful, but the speed is unbearable. Software immediately ported to C + + is not practical, so the use of joint programming, the speed of an intolerable algorithm to C + + implementation, C + + in

DescriptionMatlab as a mathematical software has its powerful graphical user interface operations, data and function visualization and numerical computing functions, and comes with many existing functions and toolkits. This article only deals with some of the basic operations of the comparison system, and at the end comes with a visual command that introduces some basic data and functions. It i
For details about how to install a Linux Enterprise Application on a Linux server, see. The installation of Matlab for linux has three ISO. We recommend that you use md5sum for verification.
The following md5sum is for reference only. It is not the original md5sum, but there is no CRC problem and file error in ISO installation.

Write this articleArticleThe purpose is not to recommend a software, butProgramPersonnel, as long as we change our thinking, we can take advantage of our professional advantages in many places, not just to help mm to kill viruses in our spare time, but to install the system to show our professionalism and uniqueness; secondly, I hope to summarize myself through the form of sharing. If it is useful to one or two friends at the same time, it will be even more gratifying.

Note: Please check the installation directory for sufficient space before installing! A full installation takes approximately 12G of space! I have the system full after installation, resulting in the inability to start the graphical interface.

Use C + + to write an IIR filterWe first design an IIR filter in MATLAB and generate a header file that reflects the frequency response characteristics of the IIR filter.Theoretical supportIIR filter is called recursive filter, it is a kind of filter with feedback. When the order is large, it can be used in series with multiple second-section filter to improve the stability of the system.A second-order nodal coefficient law:You can write the differenc

I use my MacBook to log on to a remote Linux server. MacBook is now the system version of 10.9.4. is updated, when you open Matlab reminds that X11 no longer exists, and then installs a Xquarz2.7.6. Matlab can be opened locally. However, the MATLAB desktop on a remote Linux server still cannot be opened. Restart is also invalid. Ssh–x is also invalid. There is a

Sobel Gradient Division noise resistance is good, but can not do automatic threshold, it is a great pity, Matlab is a good solution.Default 8-bit bitmap processing void Sobel (unsigned char *pin, int width, int height, unsigned char *pout) {//per row of pixels, the output image is the same as the input image int Lineby Te= (width+3)/4*4;//application output image buffer pout=new unsigned char[linebyte*height]
Record my Ubuntu+matlab installation process
Ready to install Ubuntu in virtual box under Windows7 and install matlabr2010b on Ubuntu.
Download the virtual box from the Oracle website, download Ubuntu from the Ubuntu website,
Download matlabr2010b from the Internet,
Install Virtual box and Ubuntu by default.
Then install virtual box enhancements, and set up shared folders
sudo mount-vboxsf shared/mnt/share
Mount MATLABR2010B Image
sudo mount-o
Suddenly found that the recent version of the MATLAB provides a access to Python interface, now to test, first into the MATLAB directory:
Then add sudo to execute "python setup.py install", if not added, after introducing "Matlab.engine" will be prompted to find the library:
Good, the installation is successful, now to test the use, the first is to import the relevant library, and then start the
classes for all (All-versus-all AVA) , a classifier is trained for every two classes in the M class, and a total of two class classifiers are M (m-1)/2. For example, there are three classes, 1,2,3, then you need three classifiers, They are for: 1 and 2 classes, 1 and 3 classes, 2 and 3. For a data x that needs to be sorted, it needs to be predicted by all classifiers, as well as voting to determine the final class attribute of X. However, this method needs more classifiers than the "pair of all
First, the nearest neighbor interpolation algorithm thought step:
1. Depending on the magnification, create a new size of the original image size * multiples of the 0 Matrix 2.0 matrix of each pixel value based on the original image, that is, the x,y divided by multiples of the decimal rounding (round function in MATLAB to take the nearest integer decimal) 3. For the edge of the situation to be aware
The nearest neighbor interpolation is simple and
Internet access to data, in the MATLAB forum found a good long good post, recommended for want to study SVM beginners.
Post Advantages:
1, in detail. For example: The setting problem of the Matlab Mex, the meaning of each option of Mex-setup is introduced in detail.
2, comprehensive. From the installation of LIBSVM library to the application instance, from the algorithm principle to the

Assignin
Assign value to variable in specified workspace
Syntax
Assignin (WS, ' Var ', Val)
Description
Assignin (WS, ' Var ', Val) assigns the value Val to the variable var in the workspace ws. The Var input must is the array name only; It cannot contain array indices. If var does not exist in the specified workspace, Assignin creates it. WS can has a value of ' base ' or ' caller ' to denote the MATLAB base workspace or the workspace o
Install Matlab on javastuserver, and use the X11 and Putty output Windows to Windows desktop (Environment selection). Recently, Ubuntu is a bit infatuated with Server. The memory usage is too low, and the system is stable and responsive. In this environment, running Matlab should be the most perfect. Any search on the Internet will also find that Linux Matlab is
