R2012b
6-10
The new behavior is consistent with that of other conditional statements, such as if
statements.
Compatibility Considerations
Code that uses enumerations in switch statements can behave differently in release
R2012b than in a previous release.
Cannot specify property attributes multiple times
Classes can define a property attribute only once in a properties block. Defining the
same attribute more than once in a properties block causes an error when the class is
instantiated.
Compatibility Considerations
Classes that define the same property attribute multiple times in a properties block will
error when attempting to instantiate the class. Previously, MATLAB evaluated property
attribute specifications in right to left order.
Discontinued compiler support for building MEX-files
MATLAB no longer supports the following compilers on Linux 32-bit platforms:
•
GNU
®
gcc Version 4.4.x
• GNU gfortran 4.3.x
Compatibility Considerations
To ensure continued support for building your MEX-files, consider upgrading to another
supported compiler. For an up-to-date list of supported compilers, see the Supported and
Compatible Compilers website.
Jagged array support for .NET
• To create a .NET jagged array, use the NET.createArray.
