New features and changes introduced in this version are:
New desktop features and changes introduced in Version 7.11 (R2010b) are:
You can now customize the date format that the Current Folder browser and the Command History window use to display dates, such as the dates indicated here:
Previously, the date format in both of these tools was M/d/yy (for instance, 6/4/90 for June 4, 1990) and you could not change it. Now, both tools use the operating system short date format. For details, see Customizing the Column Display.
MATLAB now integrates keyboard shortcuts preferences with File Exchange. You can access File Exchange directly from the Keyboard Shortcuts Preferences panel and find:
MATLAB keyboard shortcuts available in Version 7.9 (R2009a) and earlier releases
Keyboard shortcuts sets created by other MATLAB users
For details, see Download Keyboard Shortcut Settings Files from File Exchange .
MATLAB provides a template for classes that define enumerations. Enumeration classes enable you to define a fixed set of names representing a particular type of value. Choose File > New > Enumeration. For more information, see Enumerations.
If your system displays documentation in Japanese, you can use the Language panel in the Help Preferences dialog to instruct the Help browser to display documentation in English instead of Japanese. You can toggle between languages with the preference panel, enabling you to revert to Japanese at any time. The option changes the language used in the Help Browser and for GUI context-sensitive help, but it does not affect the language appearing in menus or elsewhere in products.
For example, the help command still provides help in Japanese after you switch the Help browser to English. The Language preference is available only when the system locale is Japanese and the Japanese documentation is installed. If the documentation for a product is not translated, the Help Browser displays the English documentation for it no matter how you set the preference.
MathWorks usually provides Japanese translations of product documentation about 2 months after new versions of products first ship. When you install the new version of a product, the previous version of translated documentation is installed in most cases.
To read the most current documentation for your release, switch the Help browser to English. After the translations of the latest documentation are available, you can download and install them in your products. At that time, you can find a link to download the latest translated documentation on the Japanese documentation start page.
New features and changes introduced in Version 7.11 (R2010b) are:
Details Panel of Current Folder Provides Preview of Graphic Files
Current Folder Browser Indicates Whether File Is Modified in Editor
Using the Current Folder browser, you can now view the files in a zip file without having to extract them. This feature enables you to:
Confirm the contents of a newly created zip file
Selectively open items from a zip file
Add or remove files from the zip file
For details, see Creating and Managing Zip File Archives or watch the Zip File Browsing video demo.
Now, when you select a JPEG, JPG, BMP, WBMP, PNG, or GIF image in the Current Folder browser, the Details panel displays a thumbnail of the image and lists its width and height in pixels. For more information, see Viewing File Details Without Opening Files or watch the File Preview Enhancements video demo.
Now, if you modify a file in the Editor, but have not yet saved the changes, the Current Folder browser indicates the file state. An asterisk (*) appears next to the name of such a file in the Current Folder browser. In addition, when you select such a file in the Current Folder browser, the detail panel reflects the modified file, not the file saved on disk. This feature is useful when you are creating zip files and want to be sure that all files included in the archive are saved and up-to-date. For details see, Viewing File Details Without Opening Files or watch the File Preview Enhancements video demo.
You can now compare any combinations of zip files, folders, and Simulink Manifests with the Comparison Tool. Right-click files or folders in the Current Folder browser and choose Compare Selected Files/Folders, or Compare Against > Choose.
For details, see Comparing Folders and Zip Files.
The Comparison Tool now provides the following capabilities:
Select what type of comparison to run from a list of possible comparison options, e.g., text, binary or XML comparison.
Enhanced MAT-file comparisons now include size, data type and change summary.
New option to ignore whitespace changes in text comparisons.
For details, see Comparing Files and Folders.
New Desktop features and changes introduced in Version 7.11 (R2010b) are:
You now can save a file that is open in the Editor to a backup file. Select File > Save Backup, and then specify a backup file name. The file that is active in the Editor when you perform the save operation remains active. If changes to the active file prove problematic, you can use the backup file to return to a known state or to compare with the active file. This comparison can help you determine where errors exist.
For information on other save options, see Save Files.
The enhanced ability to wrap MATLAB comments includes:
Wrapping an entire block of comments by selecting File > Wrap Comments.
There is no need to select the block of comments first. For details see Wrap Comments Manually.
Specifying where you want column counting to begin.
For example, if you indent comments, you can specify that you want the maximum width of comments to be 75 columns from the start of a comment, rather than from the start of a line. To set Comment formatting preferences, select File > Preferences > Editor/Debugger > Language.
The Editor now presents variables that are not local variables in a teal blue color, by default. Also by default, when you click a function or local variable, the Editor highlights it and all other references to it in a sky blue color. As demonstrated in the Variable and Subfunction Highlighting video demo, this feature makes it easier to:
Find unintentional reuses of a variable within a nested function
For details, see Avoid Variable and Function Scoping Problems.
Navigate through a file from function to function reference or variable to variable reference
For details, see Navigate to a Specific Location.
Search a file for a particular function or variable name
For details, see Find and Replace Functions or Variables in the Current File.
To disable or change the colors that the Editor uses for variable and function highlighting, see Use Automatic Function and Variable Highlighting.
When multiple documents are open and docked in the Editor, you can right-click the document tab, and then from the context menu choose:
Change Current Folder to folder-name
Add folder-name to Search Path or Remove folder-name from Search Path, respectively
Locate on Disk
This option locates the document in your operating system file browser. It is not available on Linux platforms.
Copy Full Path to Clipboard
You can use the File > Open as Text option to open a file in the Editor as a text file, even if the file type is associated with another application or tool. This feature is useful, for example, if you import a tab-delimited data file (.dat) into the workspace, and then you find you want to add a data point. For details, see Open Existing Files.
