Hi all,

I ahve a Array say A = [1 2 3 4 5 10 13 16 17 8 20 7 23 34 15];

I want to keep the position of first 5 elemnts of A unchanged. Now if any element of A don't satisfy thie following condition will come after the first 5 elements. following conditional statement are 10≤A≤16, 20≤A≤34. those elements whis are not satisfying the following condition will come before the satisfying array elements.

However, I want to see like this

A = [1 2 3 4 5 17 8 7 10 13 16 15 20 23 34 ]

I don't get the same output you specify, but I think I obeyed your rules. Did I make a mistake, or did you?

Regardless, maybe you can use my code as a basis of what you want to do.

A = [1 2 3 4 5 10 13 16 17 8 20 7 23 34 15];
A6 = A(6:end);
satisfy = (A6 >= 10 & A6 <= 16) | (A6 >= 20 & A6 <= 34);
out = [A(1:5) A6(~satisfy) A6(satisfy)]
out = 1×15
     1     2     3     4     5    17     8     7    10    13    16    20    23    34    15
