u can use something like that:
for i=1:8:24
var = x[i,1]; % here you need to do what store var in someplace else in order not to loose it

Guys I thinking about it, can you help me yet ? Idk if I do it right. so I have to task , witch consits of 3 parts:
  1. generate random bit sequence 0,1 .... I did this
  2. split generated numbers to 3 sequences for 8 bits ... you helped me with this
  3. replace bit positions within the sequence I create myself ... I have no idea how to do it , I used mathworks,google, but I still could not find the answer. I do not understand that.
Can you help me please ?
my code looks like this :
clear all;
x = randi([0 1],24,1) %generate 0,1
reshape(x,[8,3]) % splited 3,8
In command window it looks like this :
x =
1
1
