VectorCalculus[Wronskian] - 関数のリストに対するロンスキ行列の計算
使い方
Wronskian(f, t)
パラメータ
f - 代数式のリスト
t - 名前; 微分変数の指定
説明
Wronskian(f, t) コマンド () は、変数 t に関して、関数 f のリストに対するロンスキ行列を計算します。この行列は、i = 1..nops(f) について A[i,j] = diff(f[j], [t$1..(i-1)]) のように表される行列 A となります。
例
with(VectorCalculus):
Warning, the assigned names <,> and <|> now have a global binding Warning, these protected names have been redefined and unprotected: *, +, ., Vector, diff, int, limit, series
Wronskian( [exp(t),sin(t),cos(t)], t );
Wronskian( [t^3,t^4], t );
