Concatenation of Java Objects
When you concatenate Java objects, the class of the resultant object depends
on the classes of the input objects, as follows:
•If the input objects are of the same class, MATLAB makes the output object
of that class. This was true in Version 6.0 as well.
•If the input objects are of different classes, but all inherit from a common
class, MATLAB makes the output object of the common parent class.
MATLAB selects the lowest common parent in the Java class hierarchy as
the output class. This is new behavior for Version 6.1.
For example, concatenating objects of classes
java.lang.Integer and
java.lang.Double creates a new object of class java.lang.Number.
•If the input objects are of different and unrelated classes, then MATLAB
makes the output object of the
java.lang.Object class. This was true in
Version 6.0 as well.
Obsolete Fortran MX, MEX, MAT, and ENG Functions
The following Fortran MX, MEX, MAT, and ENG functions are considered to
be obsolete as of Version 6.1. Support for these functions may be removed from
a future MATLAB release.
