MATLAB: How to eliminate array which contain zero, negative values, repeated values, etc constraint

Question

Hi, I have n=6 and for example I have several set of points ( with 6 elements),

 a=[1 5 1 6 2 6];
 b=[2 5 1 6 2 5];
 c=[3 5 1 6 2 4];
 d=[0 4 1 6 3 7];
 e=[1 4 1 6 3 6];
 f=[-1 3 1 6 4 8];

I wish to eliminate the set which contain zero, negative values,elements greater than n=6 and repeated values. At the end, left set c. The others are eliminated due to:

a-repeated value 1 and 6

b-repeated value 2 and 5

d-contain zero, and 7 (which is greater than 6)

e-repeated value 1 and 6

f-contain negative value and 8 (greater than 6).

Thanks in advance.

Answer 1

a=[1 5 1 6 2 6];
b=[2 5 1 6 2 5];
c=[3 5 1 6 2 4];
d=[0 4 1 6 3 7];
e=[1 4 1 6 3 6];
f=[-1 3 1 6 4 8];
M = [a;b;c;d;e;f];
out = M(all(M > 0,2) & cellfun(@(x)numel(unique(x)) == numel(x),num2cell(M,2)),:);
