MATLAB - Cleanly read variables out of a function possibly using some type of varargout...?


Tag : matlab , By : Nic Doye

this one helps. I have function f1 which must contain subfunctions, so I can't use another script: , CREDIT TO RODY...
#Old semi-"global" variables:

function vars = f1()

    a = 1;
    b = 'hello';
    c = {[1 2 3]};
    currvars = whos;    %all variable info
    for k = 1:size(currvars, 1)
       eval(['vars.(currvars(k).name) = ' currvars(k).name ';']);
    end

end

#Function to assign variables to the calling script's/function's workspace. Variable names are determined by the single structure's fieldnames:
function setvars(func)

    vars = func;
    protected = {'If needed, put variable names you do not want here'};
    names    = fieldnames(vars);
    newnames = genvarname(names, protected);
    for k = 1:numel(newnames)
        assignin('caller', newnames{k}, vars.(names{k}));
    end

end

#Script call:

setvars(f1);

Python, simple example of multiple variables passed to another function

To fix the issue you can do I know this has been explained here before, but I still cannot figure it out for my scenario, which I explain as simple as this: , The right way to do this is with return and parameters.
def func1 ():
  a = 1
  b = 2
  return a,b

def func2 (a, b):
  c = 3
  d = 4
  e = a * c
  f = b + d

a, b = func1()
print(a, b)
func2(a, b)
>>> a, b = func1()
>>> print(a, b)
1 2
>>> func2(a, b)

PHP Setting Multiple Variables From URL Cleanly

will help you One way could be to store all the values in an array and pick up corresponding values
$parameters["price"]=array("sort_by"=>"_auto_price","order_by"=>"meta_value_num");
$parameters["year"] =array("sort_by"=>"_auto_year","order_by"=>"meta_value");
// Same for other parameters
$sorting = $parameters[$sortby]["sort_by"];
$orderby = $parameters[$sortby]["order_by"];
$sortby = $_GET['sort'] or $sortby = 'price';
 $sortby = isset($_GET['sort']) ? $_GET['sort'] : 'price';

how to cleanly use JS variables in an onclick function that are set in the page load function

may help you . To not pollute the global scope with a lot of variables (which can be overridden by other apps), I recommend you create an object with an app specific name, maybe something like this
var myAppVar = {};
window.addEventListener('load', function() {
  myAppVar.var_1 = localStorage.getItem('var_1');
  ...
}

Cleanly handling TypeErrors of multiple variables

wish helps you If the only case is that the inputs may be None you can assign empty set() instead of None:
def my_func(input_1: set, input_2: set, input_3: set) -> set:
    inputs = (
        input_1 or set(), 
        input_2 or set(),
        input_3 or set()
    )

    return set.union(*inputs)
