Octave5.1.0 installation tutorial (2020.03.09)
All the text tool, will share network disk at the end of the text, so do not worry about downloading
Octave is a programming language designed for solving linear and nonlinear numerical problems. I am into the pit in machine learning video Andrew Ng of Stanford University teacher, the teacher highly recommended Octave.
This is nonsense (installation anxious people skip)
Octave and Matlab
Who proposed conditional use Matlab
Octave is modeled on learning from Matlab software, dysfunction, installation and problems, environmental adaptability has been its low tasteless, sometimes very slow speed (than ps, ae are slow), then why not Matlab it? Good question!
First: MATLAB too, MATLAB2019b installation package, nearly 20G, compared with a much smaller Octave down (after 5.1.0 is installed 1.67G), which makes most people computer can accept.
Next: MATLAB too expensive, (shouting from the poor) essentially all of its libraries are useful to encapsulate charges, while Octave spirit of free open source philosophy has been a lot of people of all ages.
Finally: While Octave has always been a lot of problems, but it can replace MATLAB in a non-professional degree, and adaptability than MATLAB on your computer.
So, the question is, why I do not Octave? ~~ MATLAB dead, Octave when the legislation. ~ ~ Of course, better qualified people use MATLAB.
Nonsense end, start installation
Environmental ready (java, jdk) More map warning
first step: java download and install
into the official website: the Java China,
after downloading double-click to install.
Step two: JDK installation
enter the official website: the JDK's official website
Once downloaded, double-click install. Then, the focus here:
the computer environment variable configuration
This is a very important part, saying the success criteria: win + r type cmd then press Enter, enter, respectively, at the command line java, javac has output can
configure
the new system variables :
variable CLASSPATH
variable value;% JAVA_HOME% \ lib \ dt.jar ;% JAVA_HOME% \ lib \ tools.jar;.
variable JAVA_HOME
variable value D: \ JAVA \ JDK (here's your JDK installation position)
then the system variables find the path
, double-click to open after New (two):% JAVA_HOME% \ jre \ bin
% JAVA_HOME% \ bin
all the way to save the complete exit
and then type cmd carriage return after the win + r, type java at the command line, respectively, javac
similar That proved to be successful output
Octave download and install
The first step to download, enter the official website: Octave download
and then download Octave5.1.0
Do not ask me why not download 5.2.0, 5.2.0 found not start, **, and I almost do this after I reinstall the system to download and install! ! ! (Of course, the system selects the corresponding 32-bit version)
After downloading, double-click the installation, all the default, of course, you can change the installation directory
The installation is complete
Open CLI
open GUN
success
