Question

I have the following structure in matlab

superClass < handle

subClassA < superClass

subClassB < superClass

say I have a vector A of subClassA and a vector B of subClassB.

I would like to combine them like this:

superVector = [A B];

but Matlab doesn’t like this. What’s the proper way to cast the subclass back to the superclass?

Answer 1

Nevermind – it’s impossible

matlab oop help

MATLAB does not allow you to create arrays containing a mix of superclass and subclass objects because an array can be of only one class. If you attempt to concatenate objects of different classes, MATLAB looks for a converter method defined by the less dominant class (generally, the left-most object in the expression is the dominant class).
