clearvars;
clc;
a=[0 0];
while all(a)<=6
    z=[6 10 8 9 22 3 6];
    for i=1:2
    z(i)=z(randi(end));
    a(i)=z(i)+1

Check this

clc;
a=[inf inf]; % start with all elemets > 6
while ~all(a <= 6)
    z=[6 10 8 9 22 3 6];
    for i=1:2
    z(i)=z(randi(end));
    a(i)=z(i)+1
    end

I am glad to be of help! The other question seems to be a bit complicated to debug, but the main error is in the use of all() function. As you can see in my code, the comparison should be inside the all() function, not outside.

For example, instead of

all(x) > 1

you should write

all(x > 1)
