I have a class. There are some properties and anonymous functions into this class:

classdef Parabolic
  properties (Access = public)  
      a       = 0;    
      b       = 0;    
      c       = 0;  
      F       = @(t, x) 0;
        %%There are othere code
    end
properties (Access = private)     
    Z       = [];
    u       = [];
      method  = 0;
      border = @(k, psi) 0;
      %%There are othere code
  end
%%There are othere code
methods(Access = public)
function Calculate(this)
    [X, P] = meshgrid(solver.La : solver.h : solver.Lb, solver.Ta : solver.tau : solver.Tb);
    a = this.a
    b = this.b;
    c = this.c;
    this.Z = this.F(X, P); % Function
end
end
end;

I initialize some properties and after it, I execute this method it:

But I have such error:

Undefined function or variable 'a'.

What does it cause this error?

I rewrite simply example here:

Look please.

You can create some files and start my example. Please. I don't understand how to fix this bug.

Your example code here looks quite a lot different to that. For a start it uses neither global nor eval anywhere which is a big improvement, but I still don't see the purpose of using a function handle here rather than a regular class method if what you actually want is for your function to use class properties anyway.

I have use function handles as class properties before so I'm not saying it is never of use, but in this case I am not seeing the value.
