單位矩陣的意思、翻譯和例句

是什麼意思

「單位矩陣」是指一種特殊的方陣,該方陣的對角線上的元素均為1,而其他位置的元素均為0。單位矩陣通常用符號I表示,其大小由矩陣的行數和列數決定。單位矩陣在矩陣運算中扮演著重要角色,尤其是在矩陣的乘法中,任何矩陣與單位矩陣相乘,結果都是該矩陣本身。單位矩陣在數學、物理和工程等領域中廣泛應用。

依照不同程度的英文解釋

  1. A special square array with ones on the diagonal.
  2. A matrix that acts like a number one in multiplication.
  3. A matrix where all diagonal elements are one.
  4. A square matrix with ones on the main diagonal.
  5. A square matrix that does not change other matrices when multiplied.
  6. An identity matrix is a square matrix that serves as the multiplicative identity in matrix algebra.
  7. A square matrix with ones on the diagonal and zeros elsewhere, crucial for linear transformations.
  8. A matrix that satisfies the property of identity in matrix multiplication.
  9. A square matrix that is essential in linear algebra, serving as the identity element for matrix multiplication.
  10. A fundamental concept in linear algebra, representing the identity element in matrix operations.

1:Identity matrix

用法:

這是一種特殊的方陣,在數學中具有重要的意義。它的特徵是對角線上的元素為1,其他元素為0,這使得它在矩陣運算中起到類似於數字1的作用。當任何矩陣與單位矩陣相乘時,結果仍然是該矩陣本身,這是線性代數中的一個基本性質。單位矩陣的大小可以是任意的n x n,表示它可以是任意大小的方陣。
