This solution seems to run correctly in MATLAB (desktop)... can anyone tell me why it is coming back with an "Assertion Failed"?

function vec = makeRandomOrdering(n)
vec = zeros(1, numel(n));
flags = zeros(1, numel(n));
index = 1;
while (sum(flags) ~= numel(n))
pos = randi(numel(n));
if (flags(pos) ~= 1)
vec(index) = n(pos);
index = index + 1;
flags(pos) = 1;
end
end
end
