I believe for loop and if condition sometimes not the best option for the computer RAM and Memory.
Is there any function can do my job at least avoiding for loop and if condition or at least one of them?
The job is:
Assume I have this array A.
A=[1 2 6; 1 2 2; 1 2 3]
I want to save the values of the last column of the array A in a new array 'Show', when Only if the values of the last column of array A is between 2 and 5. Other elements less or above the condition will be 0 in array Show.
Is there anyway suggest for the solution please?

What have you done so far? What specific problems are you having with your code? A(:,end) is the last column of A. You can save that in Show then manipulate the elements as you like.

HG-NU - try something like
A=[1 2 6; 1 2 2; 1 2 3];
Show = A(:,end); % <---- get the last column of A
Show(Show < 2 | Show > 5) = 0; % <---- use logical indexing to set elements outside of (2,5) to zero
