Common operations in computer graphics are calculating reflection and refraction vectors(另外还有一部分的常用的操作就是反射和折射向量了). Given an incoming vector Rin and a normal to a surface N, we wish to know the direction in which Rin will be reflected (Rreflect), and given a particular ...

Compared to the other dynamic sequence containers (deques,listsandforward_lists), vectors are very efficient accessing its elements (just like arrays) and relatively efficient adding or removing elements from itsend. For operations that involve inserting or removing elements at positions other than the...

The vectors of a set of documents in a common vector space is referred as vector space model (Manning et al., 2008). Since the model is based on linear algebra, it allows vector operations, such as addition, subtraction or similarity measurements. In vector space modeling, one of the ...
