function ans = binary_numbers(n)
str2num(dec2bin(0:2^n-1));
end test suit 2 3 fails bit 1 4 5 pass help me

Test	Status	Code Input and Output
1	Pass	%% n = 2; A = binary_numbers(n); assert(isequal(class(A), 'double'))
2	Fail	%% n = 3; A = binary_numbers(n); assert(all(A(:) == 0 \| A(:) == 1)) Error: Assertion failed.
3	Fail	%% n = 5; A = binary_numbers(n); assert(isequal(size(A),[32 5])) Error: Assertion failed.
4	Pass	%% n = 10; A = binary_numbers(n); assert(isequal(size(unique(A,'rows'),1),1024))
5	Pass	%% n = 1; A = binary_numbers(n); assert(isequal(A,[0;1]) \|\| isequal(A,[1;0]))
