Can a MATLAB function edit the input?

In Python, I could define, say, a linked list via the class 'node' with attribute 'next', then define a recursive function
def addtoend(root, newnode):
if root.next == None:
root.next = newnode
else: addtoend(root.next,newnode)
I can't figure out how do implement this in MATLAB - I can define the class 'node' but MATLAB doesn't seem to allow functions to modify the input and keep it in the workspace. Is there any way around this?

You'll need your class to subclass handle. See the documentation page "Implementing Linked Lists with Classes" for details.

Thanks - in this respect isn't MATLAB much more awkward than other oop languages?

There are many benefits to the normal MATLAB function-calling behavior in which functions do not modify their inputs. I'll leave it up to you to assess the balance of pros and cons for your own work. :-)
