I have several instances in my matlab code wherein I want to pass varaibles to a function -

say,

Function A calls Function B passing an argument x.

x is updated by Function B.

Now, I want to use this updated value of x in Function A.

But this does not seem possible.

One way is that I declared x as global in function B and function A.

But if I do not want to do that, what is the best way to handle such a scenario?

Pass it back out again:

[x] = function B(x)
x = 2*x;

Call it like this, from A:

x = B(x)
