MatrixFunction

可用，但與 .wl 參考有差異

Apply a scalar function to a square matrix via its eigenvalues

形式

MatrixFunction[f, m]

已驗證的範例MatrixFunction[Sqrt, {{a, 1}, {0, b}}] → {{(a*Sqrt[b] - Sqrt[a]*b)/(a - b) + (a*(Sqrt[a] - Sqrt[b]))/(a - b), (Sqrt[a] - Sqrt[b])/(a - b)}, {0, ((Sqrt[a] - Sqrt[b])*b)/(a - b) + (a*Sqrt[b] - Sqrt[a]*b)/(a - b)}}MatrixFunction[Sin, {{a, 0}, {0, b}}] → {{Sin[a], 0}, {0, Sin[b]}}MatrixFunction[Tan, {{a, 0}, {1, b}}] → {{(a*(Tan[a] - Tan[b]))/(a - b) + (-(b*Tan[a]) + a*Tan[b])/(a - b), 0}, {(Tan[a] - Tan[b])/(a - b), (b*(Tan[a] - Tan[b]))/(a - b) + (-(b*Tan[a]) + a*Tan[b])/(a - b)}}選項
