In linear algebra, a matrix is a rectangular array of numbers, symbols, or expressions, arranged in rows and columns.
线性代数中，矩阵是一个按行和列排列的数字、符号或表达式的矩形数组。
The determinant of a square matrix is a value that can be calculated from the elements of a square matrix.
方阵的行列式是从方阵元素中计算出来的一个值。
A diagonal matrix has all its non-diagonal elements equal to zero.
对角矩阵的非对角线元素都等于零。
The transpose of a matrix is obtained by flipping the matrix over its diagonal, which switches the row and column indices of the elements.
矩阵的转置是通过将其沿对角线翻转得到的，这会交换元素的行和列索引。
The identity matrix is a square matrix with ones on the main diagonal and zeros everywhere else.
单位矩阵是一个主对角线上的元素为1，其他位置的元素为0的方阵。
Multiplying a matrix by a scalar results in another matrix with each element multiplied by that scalar.
将一个矩阵乘以一个标量会得到一个新的矩阵，其中每个元素都是原矩阵对应元素与该标量的乘积。
Matrix addition is performed by adding corresponding elements of two matrices.
矩阵加法是通过将两个矩阵的对应元素相加来完成的。
The inverse of a square matrix, if it exists, is another matrix that when multiplied with the original matrix results in the identity matrix.
如果存在的话，方阵的逆矩阵是另一个矩阵，它与原矩阵相乘的结果是单位矩阵。
