  10             有理数 <literal>r</literal> は,2つの多項式の商<literal>r=num/den</literal>です.
  11             有理数の内部表現はリストです.
  12             <literal>r=tlist(['r','num','den','dt'],num,den,[])</literal>は
  13             <literal>r=num/den</literal>と同じです.
  14             有理行列は通常の構文で定義できます.
  15             例えば, <literal>[r11,r12;r21,r22]</literal>は 2x2 行列です.
  16             ただし, <literal>rij</literal> は 1x1 有理数です.
  17             有理行列は,
  18             <literal>num</literal> および <literal>den</literal>を多項式行列として
  19             リスト<literal>rlist(num,den,[])</literal>により
  20             定義することも可能です.
