a=[0 1 1 0 1 0 1 0 1 0 1 1 1 1 ................]=30 bits how to flip it by 6 bits

[Paulo Silva]

I'm not familiar with the bit flipping concept, can you give one example or provide more information?

@Walter

I was waiting for mahaveer to show some effort :(

Just for the record here's my code:

c=[1 0 1 1 1 0 1 0 0 0 1 1 1 0 1 0 1 0 1 1 0 1 0 1 1 1 0 1 0 1 0 1 0 1 0 1] 
nbflip=6; %flip 6 bits 
v=nbflip:nbflip:numel(c); %make a vector with all the index values of c to flip 
c(v)=not(c(v)); %flip the bits

Answer 2

a(6:6:end) = 1 - a(6:6:end);

thanks its working

Answer 3

[mahaveer hanuman]

eg:c=[1 0 1 1 1 0 1 0 0 0 1 1 1 0 1 0 1 0 1 1 0 1 0 1 1 1 0 1 0 1 0 1 0 1 0 1] in every 6th element should change to 1 to 0 or 0 to 1

like 6th ,12th,18th ..... repsetive bit should change from 0 to 1 or 1 to 0 and rest of the bits should be same.

Ok now I understand but please don't accept your own answer because it ain't the solution for the problem.

I made the code but I wan't to be sure that you tried to solve the problem so I ask what have you done so far in order to solve the problem?
