i had this error :
Requested 65536x65536 (32.0GB) array exceeds maximum array size preference. Creation of arrays greater than this
limit may take a long time and cause MATLAB to become unresponsive. See array size limit or preference panel for
more information.
AT LIGNE n°3:
  1. s_old = s;
  2. s = [s(N*M-L+1:N*M);s];
  3. EYE_MAT = eye(length(s_old));
  4. PI_mat = [EYE_MAT(:, 2:end) EYE_MAT(:, 1)];
can some one help me pllllz !

If you have a PC with 16 GB RAM and the eye array alone needs 32 GB, shouldn't this tell you that you have to reduce the problem size or buy a new PC ?

Hi @amani,
I observer that you are trying to create a 65536x65536 matrix in your script. You are getting the error due the maximum array size limitations in MATLAB. You can try removing the limitations for the maximum array size by unchecking the maximum array size limit checkbox from the preference panel following this path.
MATLAB >Preferences > Workspace > MATLAB array size limit.
