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...
Python numpy.log() function computes the natural logarithm of a numpy array. numpy.log2() and numpy.log10() calculate the logarithm with base 2 and 10.

In this article, we are going to find the natural logarithm and sign of the Determinant of a Matrix using a single function numpy.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...
The LN Function in Excel The LN function returns the natural logarithm of a number in Excel. It has one argument only—number. Note: Zero or negative numbers will result in #NUM! error and non-numeric values in the #VALUE! error. Read More: How to Calculate Log in Excel Suppose you ...
Function: Compute the natural logarithm. Include: math.h Prototype: float log(float x); Remarks: A domain error occurs if the argument is not in the interval [0, +∞]. Return Value: Natural logarithm of x. File Name: log.c View chapter Book 2013, PIC Projects and Applications using C...
