Unveiling the MATLAB Chinese Localization Hack: Tackling Common Problems with Ease

# 1. Overview of MATLAB Localization

MATLAB is a powerful numerical computing and visualization software widely used in engineering, science, and finance fields. Due to its default language being English, there is a language barrier for Chinese users. MATLAB localization refers to translating the interface, help documentation, and error messages of MATLAB into Chinese, facilitating the usage for Chinese users.

Localized MATLAB can significantly improve the operational efficiency of Chinese users, reduce learning and usage costs, and thus effectively utilize MATLAB for research and development. Currently, MATLAB localization has become an essential tool for Chinese users, and it is widely applied.

# 2. Principles and Methods of MATLAB Localization

### 2.1 Structure and Composition of Localization Package

A MATLAB localization package typically consists of the following files:

| File Name | Function |
|---|---|
| `install.m` | Installation script, responsible for installing the localization package into MATLAB |
| `uninstall.m` | Uninstallation script, responsible for uninstalling the localization package from MATLAB |
| `language_pack.txt` | Localized language package file, containing localized text |
| `menu_pack.txt` | Localized menu package file, containing localized menu items |
| `help_pack.txt` | Localized help package file, containing localized help documentation |
| `custom_pack.txt` | Custom localization package file, containing user-customized localized content |

### 2.2 Key Technologies in the Localization Process

The MATLAB localization mainly involves the following key technologies:

- **Resource File Replacement:** Replacing the original resource files of MATLAB (such as text, menus, help documentation, etc.) with localized resource files.
- **Function Overloading:** Overloading built-in MATLAB functions to achieve localized functionality.
- **Object Property Modification:** Modifying the properties of MATLAB objects to achieve localized display effects.
- **Callback Function Modification:** Modifying MATLAB callback functions to achieve localized interaction behavior.

### 2.2.1 Resource File Replacement

MATLAB's resource files are mainly stored in the following directories:

MATLAB_ROOT/toolbox/matlab/resources
MATLAB_ROOT/toolbox/local/resources

The resource file replacement in the localization process mainly includes:

- **Text Replacement:** Replacing the original text files of MATLAB (such as `language_pack.txt`) with localized text files.
- **Menu Replacement:** Replacing the original menu files of MATLAB (such as `menu_pack.txt`) with localized menu files.
- **Help Document Replacement:** Replacing the original help documentation files of MATLAB (such as `help_pack.txt`) with localized help documentation files.

### 2.2.2 Function Overloading

MATLAB's function overloading mechanism allows users to define functions with the same name as built-in functions, thereby achieving custom functionality. During the localization process, built-in MATLAB functions can be overloaded to achieve localized functionality.

For example, overloading the `disp` function to achieve localized display functionality:

function disp(obj)
     % Get localized text
     text = get_localized_text(obj);
     % Display localized text
     disp(text);
end

### 2.2.3 Object Property Modification

MATLAB objects have various properties that can control the display effect and behavior of the object. During the localization process, MATLAB object properties can be modified to achieve localized display effects.

For example, modifying the `String` property of a `uicontrol` object to achieve localized button text:

% Get localized button text
text = get_localized_text('Button');

% Set button text
set(uicontrol, 'String', text);

### 2.2.4 Callback Function Modification

MATLAB's callback functions are called when users interact with the GUI. During the localization process, MATLAB's callback functions can be modified to achieve localized interaction behavior.

For example, modifying the `Callback` property of a `pushbutton` object to achieve localized button click events:

% Get localized button click event handler function
callback = get_localized_callback('Button_Click');

% Set button click event handler function
set(pushbutton, 'Callback', callback);
