Hi,
I have a query.
Generally relational operators are used to check whether some condition is true. i.e. it returns a logical vector. Is it possible that the new vector has the same values as the original vector (based on some conditions). For eg, Suppose there is a vector with 10 elements [say (1,3,2,1,4,6,7,8,5,2)]and i put a condition that the new vector is formed such that it has elements which are only less say 5. How is that possible.?
Regards

I just need one more clarification. Can the size of the vector be decreased such that it neglects the values which are now 0.
i.e. suppose my vector length was earlier 10 and now the new vector has only 7 elements because rest of them are more than 5.

Try this:
A = rand(1,10);
B = A(A<0.5);
C = zeros(size(A));
mask = A<0.5;
C(mask) = A(mask);
I think this could provide some answer.
A.
