scalar product

例句：

1. 1. The vectors are perpendicular to each other, so their scalar product is zero.
   这两个向量互相垂直，因此它们的标量积为零。
2. 2.In linear algebra, the scalar product of two vectors is a scalar value that measures the magnitude of the vectors' sum.
   在线性代数中，两个向量的标量积是一个标量值，它衡量了向量和的大小。
3. 3. The scalar product of two matrices A and B is defined as the determinant of the matrixproduct A*B.
   两个矩阵A和B的标量积定义为矩阵乘积A * B的行列式。
