MATLAB: Condition

conditionlvector

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

just

vnew = v.*(v<5)

MATLAB: Condition which reduces the size of the vector

v = [1,3,2,1,4,6,7,8,5,2];
vnew = v(v<5)  % Returns: vnew = [1 3 2 1 4 2]

Hi Javier,

as far as I understood your question you want to create a new vector with

 for i=1:lenght(A)
   if A(i)>0
     C(i) = B(i)
   end
 end

This could be done in with the for loop above, but the fastest way should be via logical indexing.

 C = zeros(size(A));
 flag_a = A >0   % is logical 1 where elements are bigger zero 
 C(flag_a) = B(flag_a);

best, Stephan
