Trouble getting two conditions to work with array While loop

1 view (last 30 days)
I'm having problems getting my while loop to work with two conditions. I'm trying to create an array that contains the numbers 3 and 7, randomizing the numbers again if it doesn't contain those two. Right now, I have this. Any ideas? Thanks!
a = zeros(1,6);
a(1,1:6) = randperm(8,6)
i = 0;
while (a ~= 3 & a ~= 7)
i = i+1;
a(1,1:6) = randperm(8,6);
end

I'm just looking for an array of 6 random numbers that includes 3 and 7. so for example, a = 8 5 3 2 7 1.

Here is one way that uses a while loop:
a(1:6) = randperm(8,6)
k = 0;
maxIterations = 200; % Whatever, the failsafe
while k <= maxIterations && sum(a == 3 | a == 7) < 2
k = k+1;
a = randperm(8, 6);
end
a % Show in command window.
