ONE-TO-ONE AND ONTO FUNCTIONS The concept of one-to-one functions is necessary to understand the concept of inverse functions. One-to-One Functions If a function has no two ordered pairs with different first coordinates and the same second coordinate, then the function is called one-to-one....
onto和one to one的区别：意思不同。onto 英 [ˈɒntə] 美 [ˈɑːntə]prep.(与动词连用，表示朝某处或某位置运动）向，朝；朝向，面向（某个方向）。one to one 英 [ˌwʌn tə ˈwʌn] 美 [ˌwʌn t...
Section 3: One-to-one, Onto, and Inverse Functions• In this section, we will look at three special classes of functions and see how their properties lead us to the theory of counting. • So far, we have the general notion of a function :X → Y, but in terms of the comparative...
内容提示: Chapter 15Functions, One-to-One, and OntoFunctions can map elements from the domain to the codomain in many ways. Afunction may “hit” every element in the codomain, or it may “miss” some. It mayassign more than one x to a y or it may assign exactly one x to each ...
onto 是漫射 台版翻译叫映成函数 映成函数(onto function)：设f：A→B，如果f(A)=B，则f是映成函数。换言之，B理的每一分子都出现作A的像，那f是映成函数。

根据离散数学及其应用第七版原版中的解释，one- to-one是指单射，onto指满射，一一对应或双射则是用bijective。参考资料：<<Discrete Mathematics and Its Applications>> 7th Edition

one-to-one,意思是"一对一"通常指一对一映射,或"一一对应映射."ONTO意思"到上" ,通常指满映射或满射,INTO意思"到内" ,通常指单射或一对一映射,设f是A到B的函数,如果对任意属于B的y,均存在属于A的x,使得f(x)=y,则称f... 分析总结。 onto意思到上通常指满映射或满射into意思到内通常指单射或一对...
one-to-one:無解或唯一解,onto:總是有解 同時為one-to-one與onto表示domain與co-domain一樣大 特性 Invertible同時為one-to-one及into,必定為 矩陣,只會有唯一解(線性獨立) 以one-on-one及onto判斷是否為invertible Rank=n, 矩陣,等於先前提到的Rank = n,Rank = m同時成立。
