MATLAB: Manipulating an anonymous function

Question

I have a handle class myClass which has a property myFunc that is a function handle which I define with an anonymous function, e.g.

myClass.myFunc = @(x) 2*x

Is it possible to use myFunc to redefine itself? I tried

myClass.myFunc = @(x) -myClass.myFunc(x)

but trying to evaluate this led to a max recursion error. My function is defined inside of a class method using a local variable like:

myClass.myFunc = @(x) localVar*x

Otherwise, I would consider using func2str, but that doesn't help because it produces the expression involving localVar which is no longer defined. Right now, I am using

myClass.myOtherFunc = @(x) -myClass.myFunc(x)

but I'd prefer not to have to create a separate property just for this.

Answer 1

tmp = myClass.myFunc;
myClass.myFunc = @(x) ~tmp(x);
