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.
