Configure libsvm in MATLAB to prevent memo

1. First, we need to download a libsvm toolbox, which can be downloaded everywhere.

2. decompress the compressed package. I decompress the package to c: \ Users \ Administrator \ Desktop \ libsvm on the desktop.

3. Open MATLAB and locate it under the following directory:

4. Enter the following code according to the process:

Welcome to Mex-setup. This utility will help you set up
A default compiler. For a list of supported compilers, see

Please choose your compiler for building Mex-files:
 
Wocould you like Mex to locate installed compilers [y]/n? N
 
Select a compiler:
[1] intel C ++ 12.0 (with Microsoft software development kit (SDK) linker)
[2] intel C ++ 12.0 (with Microsoft Visual C ++ 2008 SP1 linker)
[3] intel C ++ 12.0 (with Microsoft Visual C ++ 2010 linker)

[0] None
 
Compiler: 14
 
Your machine has a Microsoft Visual C ++ 2010 compiler located
D: \ vs2010 install. Do you want to use this compiler [y]/n? Y
 
Please verify your choices:
 
Compiler: Microsoft Visual C + + 2010
Location: D: \ vs2010 Installation
 
Are these correct [y]/n? Y

Warning: Mex-files generated using Microsoft Visual C ++ 2010 require
That Microsoft Visual Studio 2010 run-time libraries be

If you plan to redistribute your Mex-files to other MATLAB
Users, be sure that they have the run-time libraries.

Variables with more than 2 ^ 32-1 elements. In the near future
You will be required to update your code to utilize the new
Api. You can find more information about this:

If the data in the dataset can be loaded and displayed in red, we can think that the configuration is complete.

It should be noted that the absolute address of the folder after installation should not be moved as much as possible, or an error may be reported when the folder is run again...

Note: the blue part is the code that we need to manually enter. The last line of red is the final output.

In this way, other excellent posts on the MATLAB forum can be viewed.
