What is your mental model of it? How is it implemented? Which strengths and weaknesses does it have? MATLAB GC vs. Python GC?
I sometimes see strange performance bottlenecks when using MATLAB nested functions in otherwise innocuously looking code, I am sure it is because of GC. Garbage Collector is an important part of VM and Mathworks does not make it public.
My question is about MATLAB's own heap and GC! Not about handling of Java/COM objects / preventing "out of memory" errors / allocation of stack variables.
EDIT: the first response is actually the meta-answer "Why should I care?". I do care because GC manifests itself when implementing linked list or MVC pattern.
