1、代码:using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.IO;using System.Text;namespace ConsoleApplication1 class Program static void Main(string args) StreamReader sr; sr = File.OpenText(E:矩阵求均值.txt); string line = null; while (sr.Peek() -1) line += sr.ReadL
2、ine(); string a = line.Split(,); string s = a1; string b = System.Text.RegularExpressions.Regex.Split(s, s+); float ,c=new float83,8; string, d = new string83, 8; float avg = new float8; for (int i = 0; i 83; i+) for (int j = 0; j 8; j+) di, j = b8 * i + j + 1; for (int i = 0; i 83; i+) for (int j = 0; j 8; j+) ci,j=float.Parse(di,j); Console.Write(矩阵每列的平均值为avg= ); for (int i = 0; i 8; i+) float m = 0; for (int j = 0; j 83; j+) m = m + cj, i; avgi = m / 8; Console.Write( + avgi); Console.WriteLine(); 运行结果截图:
