As you are resistant to the correct and accurate solutions you have been
shown, you need to add the following hack to your program:

assignin('caller', 'G', G);

===================

But now you understand that it does not get destroyed, correct? When you run the function

function G=test
...
G=....; %This doesn't
end


the result G is just a temporary variable that will be assigned to the variable "ans" in the workspace where you issued a call to test(). That will always automatically happen unless you specifically assign the result to something else.

It's a dangerous solution. If you don't understand why it's unnecessary, you're bound for trouble.

Some people just don't learn until the light matches burn their fingers. :(
