a(1,a == 1) = -1;
a(1,a == 0) = 1;
I am not sure what does this line really do? Can someone explain to me?
2- Does anyone know the function of correlation, auto and cross? I want to build smooth function.

  1. Create a test a array of integer values including at least some ones and zeros and test it
  2. Read the documentation, first.

Look at what this does.
a=randi(2,1,20)-1
a(a==1)=-1%same as a(1,a==1)=-1
a(a==0)=1%same as a(1,a==0)=1;
