varn
多項式の記号変数
呼出し手順
[symb]=varn(p) [pm]=varn(x,var)
パラメータ
- p
多項式 (または多項式行列)
- symb
文字列
- x
多項式または多項式行列
- var
記号変数 (文字列)
- pm
行列または多項式行列
説明
symb=varn(p)
は,
多項式p
の記号変数 symb
を返します
(すなわち,varn(poly(0,'x'))
は 'x'
です).
varn(x,'s')
は,x
と
同じ係数を有し,'s'
を記号変数とする
多項式行列を返します(変数名の変更).
例
s=poly(0,'s');p=[s^2+1,s]; varn(p) varn(p,'x')
