模拟退火算法来源于固体退火原理，将固体加温至充分高，再让其徐徐冷却，加温时，固体内部粒子随温升变为无序状，内能增大，而徐徐冷却时粒子渐趋有序，在每个温度都达到平衡态，最后在常温时达到基态，内能减为最小。 (Simulated annealing algorithm derived from solid annealing principle, the solid is heated to a sufficiently high, let it cool slowly, when heated, solid particles with temperature becomes disordered state, the internal energy increases, while slowly cooling the particles gradually increasingly ordered at each temperature to reach equilibrium, and finally reach the ground state at normal temperature, which can be reduced to a minimum.)

产生、播放DTMF音频，基于Goertzel算法估计DTMF音频，完成双音多频(DTMF)信号的检测(Generating, playing DTMF tones, DTMF tones based on the estimated Goertzel algorithm to detect the completion of dual tone multi-frequency (DTMF) signal)

用于轴的校核。之前做课程设计的时候自己写的，根据《机械设计课程设计》王军 田同海 何晓玲著这本书上的公式编写。(According to the formula design of mechanical design, Wang Juntian and Hai He Xiaoling wrote the formula in this book.)

这是一个三次样条插值的.m程序 输入的是一个二维数组A(Nx2) 插值方法为: S(x) = A(J) + B(J)*( x - x(J) ) + C(J)*( x - x(J) )**2 +D(J) * ( x - x(J) )**3 for x(J) <= x < x(J + 1) (This is a cubic spline interpolation. M program input is a two-dimensional array A (Nx2) interpolation method: S (x) = A (J)+ B (J)* (x- x (J ))+ C (J)* (x- x (J))** 2+ D (J)* (x- x (J))** 3 for x (J) )
