Desktop Tools and Development Environment

You can use the new View menu to choose the columns to display, to specify the sort
order for a column, and to apply grouping for any attribute. In the previous version,
you performed these actions using the column header and its context menus, which
you can still do (but only on Microsoft Windows platforms). For more information, see
Sorting and Grouping Files and Folders.
A new Description column displays the brief description for files and directories
in the current directory. To show the column, use View > Choose Columns.
Descriptions include the first help line in a MATLAB program file, and a model file's
description, which is useful because you do not need to start the Simulink software to
view it. The description is the same one that appears with the details for a selected
file. For more information, see Viewing Help for a MATLAB Program File.
If you try to rename a MATLAB program file in the Current Directory browser to an
invalid name, such as *myfile.m, a warning appears, notifying you about the name
problem. If you want to run the ile, change the file name to a valid one. For more
information about what a MATLAB file name requires to be valid so you can run it,
see Naming Functions.
When you right-click a FIG-file in the Current Directory browser, there is a new
option to open the figure in GUIDE.

Many M-Lint Messages Now Extend to Provide an Explanation and Suggested Action

over an M-Lint indicator that has an extended message, the message appears as a link:
