In the following example, function myfun1 is not callable if the current working directory
is set to dir1. The same holds true for myfun2 if the current working directory is set to
dir2.
\home\matlab\@myobj\dir1\myfun1.m
\home\matlab\@myobj\dir1\dir2\myfun2.m
This behavior existed in the R2006b release, as well as in this release.
Compatibility Considerations
You will no longer be able to call a file that is one or more levels beneath a MATLAB
class directory if your current working directory is set to that same directory.
Improved Performance on Certain Platforms and Operations
As of release R2006b, MATLAB offers improved performance in the following areas:
• Improved performance on 64-bit Windows XP and Linux platforms. This is
independent of the size of data set in use.
• Faster scalar indexing into cell arrays.
• Faster assignment of cell array data to variables.
Technique to Conserve Memory on Windows Vista
To conserve memory on machines running Windows Vista, you can reduce the amount of
virtual memory space reserved by the operating system by using the command:
BCDEdit /set increaseuserva 3072
More documentation on this option can be found at the following URL: http://

ispuma Function Deprecated
Because MATLAB no longer supports Mac OS X 10.1, the ispuma function always
returns false in this release, and also displays a warning message that the function is
now deprecated. Support for ispuma will be removed in a future release of MATLAB.
