z % unmodified since scope was base
end

z=1;
func_two(3);

z % modified since scope was base

z = 2
z = 3

function func_one(a)
assignin('caller', 'z', a);
end

function func_two(a)
z=2;
func_one(a);
z % modified since scope was caller
end

z=1;
func_two(3);

z = 3
z = 1

Comments

If con is 'base', the assignment is performed in the base scope (outside of any function scopes).

If con is 'caller', the assignment is performed in the scope in which the current function is called.
