M and T are 1024*366 matrix want to make a separate matrix that follow some condition?

M and T are 1024*366 matrix want to make a separate matrix that follow some condition

A=[];
  nnn=1;
  for i=1:1023
      nn=1;
  for j=1:965
  if (T(j,i)>500 && T(j,i)<600)
      A(nn,nnn)=M(j,i);
      A(nn,nnn+1)=T(j,i);
  end
  end
  nnn=nnn+4;
  end

This error How can I solve?

Attempted to access T(1,967); index out of bounds because size(T)=[1024,966].

If M and T are 1024 * 366 then why is your "j" loop running to 965? And since your "i" loop is running to 1023 and it is the first dimension that is as large as 1024, then why are you using "i" to index the second dimension of the matrix instead of the first ?
