combine/piecewise - combine を区分的な関数に適用
使い方
combine(f, piecewise)
combine(f)
パラメータ
f - 任意の式
説明
combine 関数が区分的な関数の引数に適用されます。
2つの区分的な式から1つの区分的な式を作るには、convert(expr, piecewise, var) を用います。
例
combine( piecewise(x>0, cos(x)^2+sin(x)^2, exp(x)^2*exp(y)) );
combine( piecewise(x<1, exp(x)*exp(-2*x), x>3, 4*sin(x)^3) );
参照
piecewise, convert[piecewise]
