Many problems that require true parallel computing are solved via scientific calculations that perform operations on vectors and matrices.
许多需要真正的并行计算的问题都通过在向量和矩阵上执行操作的科学计算解决了。
How do we decide if two vectors are parallel?
我们平时怎么验证两个向量平行呢？
Well, that's because my line is perpendicular to the normal vectors, so it's parallel to the planes it's parallel to all the planes Now, why is it in the planes instead of parallel to them?
那是因为这条线垂直于全部法向量，所以它平行于全部平面，所以它平行于全部平面，为什么它在面内而不是平行于该面？
