Class Does Not Have Property
If a MATLAB® class has a method, mymethod
, that returns a handle
class with a property, myprop
, you cannot generate code for the
following type of
assignment:
obj.mymethod().myprop=...
For example, consider the following classes:
classdef MyClass < handle properties myprop end methods function this = MyClass this.myprop = MyClass2; end function y = mymethod(this) y = this.myprop; end end end
classdef MyClass2 < handle properties aa end end
You cannot generate code for function
foo
.
function foo
h = MyClass;
h.mymethod().aa = 12;
h.mymethod()
returns a handle object of type
MyClass2
. In MATLAB, the assignment h.mymethod().aa = 12;
changes the
property of that object. Code generation does not support this assignment.Solution
Rewrite the code to return the object and then assign a value to a property of the object.
function foo
h = MyClass;
b=h.mymethod();
b.aa=12;
