说明：  自己写的基于matlab的WAV声音文件报警的仿真程序(Write their own based on the WAV sound files matlab simulation program alarm)

多功能读入MATLAB的函数，可定义其参数(A signal object contains signal data, that is a collection of real or complex valued samples. A signal can be one or multi-dimensional. The number of dimensions is the number of axes that are needed to describe the the data.)

单步单纯型法，输入为系数矩阵，右端向量，目标函数系数向量，基变量下标，非基变量下标和基变量初始值(Step simplex method, the input for the coefficient matrix, right vector, the objective function coefficient vector, the base variable subscript, superscript and the non-basic variable initial value of base variable)

说明：  Matlab 实现多项式曲线拟合（正弦曲线），交叉验证（十折交叉验证）(poly fit ，cross validation)
