实验三-M函数和M文件的编写与应用以作三道题

Matlab在电子信息类中的应用实验专业：成绩：姓名：学号：实验三:M函数和M文件的编写与应用实验目的: 熟悉M函数和M文件的编写与应用实验内容:编写M函数实现：求一个数是否为素数，再编写一主程序(脚本文件)，要求通过键盘输入一个整数，然后判断其是否为素数。编写求解方程ax2+bx+c=0的根的函数，这里应根据b2-4ac的不同取值分别处理，并输入几组典型值加以检验。有n个人围成一圈，按序列编号。从第1个人开始报数，数到m时该人退出，并且下一个从1重新开始报数，求出出圈人的顺序(n>m，例如n=20，m=7)。编写M函数计算（，步长0.01）。(5)设
