Concatenation for heterogeneous arrays
C = cat(dim,A,B)
If A and B are of the same class, the class of the resulting array is unchanged.
If A and B are of different subclasses of a common superclass that is derived from matlab.mixin.Heterogeneous, then the result is a heterogeneous array and the array's class is that of the most specific superclass shared by A and B.
The cat method is sealed in the class matlab.mixin.Heterogeneous and, therefore, you cannot override it in subclasses.
Scalar dimension along which to concatenate arrays
Object array derived from the same root subclass of matlab.mixin.Heterogeneous as B
Object array derived from the same root subclass of matlab.mixin.Heterogeneous as A
Array resulting from the specified concatenation. The class of this array is that of the most specific superclass shared by A and B.
