Compatibility Considerations
Because mmreader imports Motion JPEG 2000 files, the function
mmreader.isPlatformSupported always returns true on Windows, Macintosh, and
Linux platforms. For a list of file formats that mmreader supports, and the requirements
to read these formats on each platform, see the mmreader reference page.
Minimum Sample Rate for audioplayer
If you specify a sample rate less than 80 samples per second, audioplayer generates an
error with the following ID:
MATLAB:audioplayer:positivesamplerate
Compatibility Considerations
In previous releases, the error ID on Windows platforms for low sample rates was:
MATLAB:audioplayer:negativesamplerate
Change any references to this identifier to:
MATLAB:audioplayer:positivesamplerate
Documentation Changes: File I/O and Data Import and Export
The function category “File I/O” is renamed “Data Import and Export.” It appears
immediately below the category “Desktop Tools and Development Environment.”
In the MATLAB User Guide, Data Import and Export content previously appeared in the
Programming Fundamentals documentation. The User Guide now includes a stand-alone
topic for Data Import and Export.
Object Array Property Indexing
Object array indexing operations on properties now return an error for improper array
references. Before MATLAB 7.9, an expression such as:
obj.Prop(n) % for non-scalar obj is invalid if Prop is a property
did not return an error. MATLAB 7.9, you can reference or assign properties from scalar
objects only by entering:
