Many MathWorks® products provide versions of the documentation translated from English to Japanese.
The new version of most products installs the translated documentation from the previous version and the English documentation for the current version. To view the English documentation, access the Environment section on the Home tab, and click Preferences. Select MATLAB > Help, and set the Help Language preference to English.
The Language preference is available when the system locale is Japanese and the translated documentation is installed. The preference changes the language only in the Help browser and context-sensitive help. If the documentation for a product is not translated, the Help browser displays the English documentation.
When the translated documentation is available, you can view
it by setting your Help Documentation Location preference
to view documentation on the web. Alternatively, download it from
the MathWorks website at
For information about documentation in other languages, contact your MathWorks sales and service office.
