This is my code s1=[216 46; 176 127; 227 131; 256 170; 176 187];
a=s1(:,1);
disp(a);
b=s1(:,2);
disp(b);
when i execute this i get 216 176 227 256 176 in a and 46 127 131 170 187 in b.
now i want to access individual values from a and b like i want to print only 2nd value of a and 2nd value of b. How to do it.

If you want the second element of a, then use indexing to get the second element of a:
>> a(2)
ans = 176
Or simply from the original array:
>> s1(2,1)
ans = 176
Basic MATLAB concepts (such as how to use subscript indexing) is covered in the introductory tutorials, which are highly recommended for all beginners:
