Interactive Illustration 9.3: The function y=x2 is an example of a mapping from the real numbers N=R to the set of real numbers M=R. In linear algebra, the term mapping is traditionally used instead of function, but the meaning is the same, i.e., you start out with an item x,...

(1) A mapping T : Rn-Rm is said to be onto Rm if each b in Rm is the image of at least one x in Rn (满射) (2) A mapping T : Rn-Rm is said to be one-to-one if each b in Rm is the image of at most one x in Rn (单射) §1.9 The Matrix of A Linear ...
For $x,y\\in {R}^{n}$ it is said that $x$ is majorized by $y$ if there is a double stochastic matrix $A\\in {M}_{nimes n}$ such that $x=Ay$ (denoted by $x\\prec y$). Suppose that $\\Phi$ is a linear mapping from ${R}^{n}$ into ${R}^{n}$, which is ...

While "map" is probably the most commonly used term, we can interchangeably use the terms "mapping", "transformation" and "function". Example Let be the space of all column vectors having real entries. Let be the space of column vectors having real entries. Suppose the map associates to ...
