| 中文摘要: |
| 介绍数、代数的起源和发展,阐述代数表达的内涵和外延,讨论特殊矩阵命名的原则和惯例,提出了用大写的黑体、斜体英文O 表示零矩阵,小写的黑体、斜体英文o表示零向量,以及用数字零表示一个矩阵或向量中的零元素的建议。 |
| 英文摘要: |
| Origin and development of number and algebra are introduced. And their meanings and extension in the mathematic representation are discussed. Then rule and convention that special matrices are named are described. Finally, it is suggested that a null matrix is represented with upper-bold italic English letter O, a zero vector with lower letter o, and a zero entry in a matrix or a vector just with scalar number 0. |
