Noun:
-
a real number (a scalar) that is the product of two vectors
- For this reason the inner product is called also the scalar product.
为此，内积也叫做纯量积。
- There are many different types of abstract space in mathematics, for examples, vector space, inner product space, etc.
数学上存在各种不同的抽象空间，例如向量空间，内积空间等。
