例如，pdf后端会尽可能使用矢量计算(只在必要时生成图像)，而PostScript后端实际上会为每个页面生成一个大图像。

For example, the PDF backend is vector-based where possible (only falling back to images when necessary), whereas the PostScript backend essentially generates one large image per page.

本文讨论多元质量数据的矢量分析方法，几何变换，坐标旋转和初始变量的主分量计算不同变量的主分量值。

This paper deals with the multivariate vector analysis of quality data by geometric transformation, rotating coordinates and computation of the principal component of initial variables.

Once you've got that, you can do minus 7 times a vector Just take the vector, multiply it by Pi and flip it over.

明白这点之后,你就可以计算-7乘以矢量,只需用 π 去乘以那个矢量,然后将其方向调转
