原声例句
Linear algebra

What this expression is saying is that the matrix vector product A times V gives the same result as just scaling the eigenvector V by some value lambda.

这个表达式说的是矩阵向量乘积A乘以V得到的结果和特征向量V乘以某个值是一样的。

Linear algebra

Then when we apply m to to that vector, you can work out the matrix vector product to get zero negative too, which becomes the 2nd column of our composition matrix.

然后当我们把m作用到这个向量上 你可以算出矩阵和向量的乘积也得到负0 这就变成了复合矩阵的第二列。

矢量积 Cross product

（重定向自Vector Product）
在右手坐标系中的矢量积
以矢量定义的平行四边形。

叉积（英语：Cross product）是一种在矢量空间中矢量的二元运算。与点积不同，它的运算结果是一个矢量而不是一个标量。两个矢量的叉积写作 \mathbf{a} \times \mathbf{b}，也称作外积（英语：Outer product）或矢量积（英语：Vector product）。叉积与原来的两个矢量都垂直。

Cross product 向量积

（重定向自Vector Product）
The cross-product in respect to a right-handed coordinate system
Finding the direction of the cross product by the right-hand rule
The cross product a × b (vertical, in purple) changes as the angle between the vectors a (blue) and b (red) changes. The cross product is always orthogonal to both vectors, and has magnitude zero when the vectors are parallel and maximum magnitude ‖a‖‖b‖ when they are orthogonal.
According to Sarrus' rule, the determinant of a 3×3 matrix involves multiplications between matrix elements identified by crossed diagonals

In mathematics and vector calculus, the cross product or vector product (occasionally directed area product to emphasize the geometric significance) is a binary operation on two vectors in three-dimensional space (R) and is denoted by the symbol ×. Given two linearly independent vectors a and b, the cross product, a × b, is a vector that is perpendicular to both a and b and therefore normal to the plane containing them. It has many applications in mathematics, physics, engineering, and computer programming. It should not be confused with dot product (projection product).
