I assume that output of below Matlab code is required with reason.
x = 0;
a();
function a()
x = 2;
b();
disp(x);
end
function b()
x=2;
x = x+1;
disp(x);
end
(console.log(), var and ++ are not a valid Matlab commands)

Reason:
x is a local variable and the scope of this variable is within the function only.
Among the display functions: disp(x) inside function b() is executed 1st, where the value of x is 3 (x=2; x=x+1). Then disp(x) inside function a() is executed, where the value of x is 2 (x=2)
