Try randperm().

in my code the total number of rows is 4.

Lets say (1,2,3,4). I am forming 2 groups and I am running the code with respect to 4 iterations. For each iterations the number of rows displayed keeps on changing and i am getting the following result.

iteration-1
rows = 3     4
rows = 1     2
iteration-2
rows =4     1
rows =3     2
iteration-3
rows =2     3
rows =4     1
iteration-4
rows =1     2
rows =3     4

But what i actually is need the number of rows need to be fixed for every iterations. Could you please help me on this.

In the output you show, the number of rows is the same each time, 2 rows each time.

set the same rng() for every iteration.

Prabha Kumaresan 2018-4-17

when i used rng() the number in each rows remain fixed whereas the gain corresponds to the rows also getting fixed.My aim is to run with different iterations by fixing the number in each rows which corresponds to different gain values for each iteration.so could you please help me how to fix the number in each rows with different gain values corresponding to different iterations.
