So, speed, which is the scalar quantity is going to be just the magnitude of the vector, V.

因此，速度的大小即是,矢量V的模长。

In scalar code on the spe, declaring scalar values as vectors and vector Pointers (even if you aren't using them as vectors) can speed up code because it doesn't have to do unaligned loads and stores.

在SPE上的标量代码中，将标量值声明为向量和向量指针(即使没有将它们作为向量使用)可以加速代码的执行，因为这样就不会执行非对齐的加载和存储操作。
