# Introduction of MATLAB Software for data visualization analysis

**MATLAB (Matrix Laboratory)**is a Engineering computing environment developed by MathWorks, Inc. for computing and visualizing data. MATLAB is an interactive system and as a programming language, the basic element of which is a data array (scalar, vector, matrix and double matrix). Besides matrix operations, MATLAB also offers the same programming features as other computing languages.

MATLAB
can be executed on Windows and LINUX systems. The MATLAB software package
contains many functions for data analysis. There are also several Toolboxes
that can be used to expand the capabilities of MATLAB.

In
this computational statistics article, we will discuss MATLAB version 9.4 2018.
When starting MATLAB, a Command Window window will appear or it can be called
the Command Window with a prompt that will be used to write command code.
Normally, in MATLAB there are other windows besides the Command Window namely
Workspace, Details folder and others.

**WINDOW MATLAB**

There
are several windows (Window) in MATLAB. These windows include,

COMMAND
WINDOW. The Command Window that I mentioned earlier that the Command Window is
used to write command code that will produce numeric output or the results of
logical analysis (IF Then), errors in typing in the Command Window and others.
Where the Windows Command display is shown in the image below,

WORKSPACE
MATLAB will always remind ENTER commands and all variable values made. These
variables are stored in the Workspace window. The variable can be called at any
time by typing the name of the variable in the Command Window then ENTER. In
MATLAB Temp, temp and TEMP represent different variables. Variables can be
viewed and edited in a window like a spreadsheet by double-clicking on the
variable name. Below is an example of a Workspace display.

COMMAND
HISTORY. This window displays statements that are executed in the command
window window. Command History can be used to view, copy and execute
statements.

HELP.
This window contains information about procedures for using the MATLAB command
code. Code Description Commands that are on the HELP are standard MATLAB
commands or toolboxes that have been installed.

FIGURE
/ GRAPHIC. This window will automatically appear to display images or graphics
made by MATLAB. Where only one window figure can be opened at a time.

EDITOR
/ DEBUGGER. This window is used for making m-files. M-file is a collection of
MATLAB code commands for a specific purpose. This window can be accessed using
the pull-down menu, by selecting File ==> New ==> M-File.
