Only if the componentvectors are on a straight line will the length of the vector for the sum be equal to the sum of the lengths of these components or to their difference.
只有当几个分矢量在一直线上,那么表示其和的矢量长度才会等于这些分量的长度和或它们的差。

Multiplies two vectorscomponent-wise.
两个矢量组件对应相乘。

Then a fit combinatory for the variables corresponding to component 1of the vectors in each set are carried out.
