Write function instead of script. For example
function [a b c] = my_function
q = 1;
s = 2;
e = 3;
r = 5;
a = q+s;
b = e - r;
c = rand(1);
And run it in this way:
[a b c] = my_function
Or you can use clearvars (clear) function. For example:
q = 1;
s = 2;
e = 3;
r = 5;
a = q+s;
b = e - r;
c = rand(1);
clearvars s e r q
