...c = ij a + ij b Def： 纯量乘法 (scalar multiplication) 11 n m A =[ ij a ]，r 为实数，则rA 称为纯量积(scalar multiple)， 若rA=B=[ ij b ]，则B 为m×n 矩阵，且 ij b =r ij a Ex2.
The functions can be coded to return a single value (for scalar functions) or multiple values (for table functions).
函数可以返回单一值(对于标量函数)或多个值(对于表函数)。

It can be treated as a scalar value or a pointer to a structure containing multiple parameters, or it can be ignored.
