一、一一对应函数(one-to-one function) 若函数 f 从未取同一个值至少两次,即对任意 x1≠x2 有f(x1)≠f(x2) ,则称其为一一对应函数. 二、水平线检验 当且仅当没有任何一条水平线与函数图象曲线相交超过一次时,该函数是一一对应的. 如下例: 图记1.6-1 图左曲线相应的函数一一对应,图右的不一一对应...
function is one of the most useful functions in mathematics, with applications to mathematical models throughout the physics, biologic and other fields of science and life. Logarithms also have practical uses in many fields of life and nature. For example, each chamber of the shell of a ...

In this article, we are going to find the natural logarithm and sign of the Determinant of a Matrix using a single functionnumpy.linalg.slogdet(a). It returns a tuple in order of (sign and log(det)). Example: The determinant of a 2-D array [[a, b], [c, d]] is ad - bc ...
