How to use a variavle calculate by a code to another code?

2 views (last 30 days)
Hi all,
I hope that everyone is doing well.
I have a code this code calculate the value of a variable y.
I would like to export y only to another code and I do not wana use sub function because both codes are long and I may used several same characters at different stage.
Thanks and regards

The simple, efficient, and most robust way to pass data between function workspaces is to pass input/output arguments:

Im not sure i get your point about long code and reused variables. Its also a bit unclear what kind of code we are talking about.
Do you have 2 scripts script_A and script_B and want to calculate variable y in sript_A and then use it in script_B? In that case script_A will write y into the matlab base-workspace where it will be available to any code that is run after it, including script_B.
script_A
y = rand;
script_B
z = y;
Now you could type in the console:
>>script_A
>>script_B
In case we are talking about functions (which do not have direct access to the base-workspace) you could define y as a function return value.
function y = function_A
y = rand
end
And now you can use y in another script with
z = function_A;

Thank you a lot, it is exactly what I am looking for.
but what I want to do is to clear all the variable in script A except for y that I will use it later in script b.
I meant by long is that I used a lot of abreviation for variables and I repeated it in scrtipt B this is why I wanna clear all except for y.

In that case i would suggest you simply turn script_A into a function and only return the variables you need. Functions have a seperate workspace from the base workspace and you wont have to clear those variables manually once the function is finished.
