Matlab: directly access a specific return value of functions


Matlab: directly access a specific return value of functions

Hope this helps Unfortunately it cant be done in matlab, it is just not supported. The only way I know of, that is somehow elegant, is to create itemgetter (something ala itemgetter in python). For example,
code :
itemgetter = @(r, idx) r{idx}


#now get first returned argument
itemgetter(regexpi(str,'[a-z]+','match'), 1)

To fix the issue you can do Not really, they are, basically, exactly the same. One uses encapsulation (getter/setter) to better protect the data and for simple usage. You're supposed to use this style (for security).
The other allows for better usage when names(keys) are unknown and for arrays and loops. Use .key() and .length to iterate through your storage items without knowing their actual key names.

I wish this help you Use ~ to suppress x output. Only available in later versions of matlab (=> r2009b).
code :
[~, y] = fminbnd(h, -10, 10);

I wish this helpful for you I've solved my problem. Only it was necessary to define global the variable 'number' in all the necessary functions. now easily i can change the value of 'number' in GUI or in A() function. no need to 'set' function.
code :
main()
  %some code
  A();

  function A()
    global number;
    disp(number);
    number = 5;
  end
end
function B_Callback(hObject, ~, handles)
global number;
number = 2;
guidata(hObject, handles);

this will help You can't apply & to a value like that (unless it's a composite literal). From the spec:
Should a functions return value be assigned to a variable or used directly?

wish helps you
I am wondering if it is better to assign the values of each function to a variable then compare the variables.
