[Roberto Ratti]

Follow-up Comment #1, bug #45754 (project octave):

Same problem (and same solution) for functions satlin and satlins



function a = satlin(n)
  
  ####### here commented, the original code #########
  ##if (n<0)
  ##  a = 0;
  ##elseif (n>=0 && n<=1)
  ##  a = n;
  ##else
  ## a = 1; # if n>1
  ##endif
  ###################################################

  for i=1:size(n, 1)
   for j=1:size(n, 2)
    if (n(i,j)<0)
     a(i,j) = 0;
    elseif (n(i,j)>=0 && n(i,j)<=1)
     a(i,j) = n(i,j);
    else
     a(i,j) = 1; # if n>1
    endif
   end
  end

endfunction

function a = satlins(n)

  ####### here commented, the original code #########
  ##if (n<-1)
  ##  a = -1;
  ##elseif (n>=-1 && n<=1)
  ##  a = n;
  ##else
  ##  a = 1; # if n>1
  ##endif
