Programming
23-25
There are changes in how MATLAB displays built-in functions using which:
In MATLAB 7.0.4 (R14SP2),
which -all int32
\\matlab\toolbox\symbolic\@sym\int32.m % sym method
\\matlab\toolbox\matlab\datatypes\int32.bi % Shadowed
\\matlab\toolbox\matlab\datatypes\int32.m % Shadowed
In MATLAB 7.1 (R14SP3),
which -all int32
built-in (\\matlab\toolbox\matlab\datatypes\int32)
\\matlab\toolbox\symbolic\@sym\int32.m % sym method
New Warning About Potential Naming Conflict
If you change directories (cd) or add a new directory to your current MATLAB path,
and the new directory contains an M-file having the same name as a MATLAB built-in
function, MATLAB now displays a warning alerting you to the potential naming conflict.
For example,
Warning: Function D:\test\matlab\disp.m has the same name as a
MATLAB builtin. We suggest you rename the function to avoid a
potential name conflict.
In general, any file system event that leads to path refreshing in MATLAB can trigger
this warning if the directory involved in this event has such a user function under it.
Compatibility Considerations
MATLAB might generate warnings about naming conflicts that did not appear in
previous versions. To avoid this warning, renaming your M-files that have name conflicts
with built-in functions.
