中文说明：二分法是一种逐步二分区间[a,b]，通过判断两端点函数值的符号，进一步缩小有根区间，将有跟区间的长度缩小到充分小，从而求出满足精度要求的跟x的近似值，用以解决非线性方程求解的一种简单方法，此次上传的文件包括三种不同的二分法MATLAB程序。
English Description：
Dichotomy is a kind of step-by-step dichotomy interval [a, b]. By judging the symbols of function values at both ends, the root interval is further reduced, and the length of the heel interval is reduced to sufficiently small, so as to find the approximate value of heel X that meets the accuracy requirements, which is a simple method to solve nonlinear equations. The uploaded file includes three different dichotomy matlab programs.
