can any one help me for the code

Si(t) € {0,1}

Answer 1

[Thorsten]

 Si = rand(1,100)>0.5; % fake some sample data
 f = rand(1, 100);
 fmin = 0.3;
 fmax = 0.7;

 Siplus = Si; % the otherwise case
 ind = Si == 1 & f < fmin; Siplus(ind) = 0;
 ind = Si == 0 & f > fmax; Siplus(ind) = 1;

You can also write it more consicely without ind:

 Siplus = Si; 
 Siplus(Si == 1 & f < fmin) = 0;
 Siplus(Si == 0 & f > fmax) = 1;
