<para>
A rational <literal>r</literal> is a quotient of two polynomials <literal>r=num/den</literal>.
The internal representation of a rational is a list.
- <literal>r=tlist('['r','num','den','dt'],num,den,[])</literal> is the same as <literal>r=num/den</literal>.
+ <literal>r=tlist(['r','num','den','dt'],num,den,[])</literal> is the same as <literal>r=num/den</literal>.
A rational matrix can be defined with the usual syntax
e.g. <literal>[r11,r12;r21,r22]</literal> is a 2x2 matrix where <literal>rij</literal> are
1x1 rationals.
<para>
有理数 <literal>r</literal> は,2つの多項式の商<literal>r=num/den</literal>です.
有理数の内部表現はリストです.
- <literal>r=tlist('['r','num','den','dt'],num,den,[])</literal>は
+ <literal>r=tlist(['r','num','den','dt'],num,den,[])</literal>は
<literal>r=num/den</literal>と同じです.
有理行列は通常の構文で定義できます.
例えば, <literal>[r11,r12;r21,r22]</literal>は 2x2 行列です.
