C#程序说明下三角矩阵
对于下三角矩阵，将主对角线上的所有元素设置为零。
设置以下条件-
if (i >= j)
Console.Write(A[i, j] + "\t");
else
Console.Write("0\t");示例
您可以尝试运行以下代码以显示下三角矩阵。
using System;
using System.Linq;
class Demo {
static void Main() {
int m, n, i, j;
Console.Write("Enter number of rows and columns of the matrix ");
m = Convert.ToInt16(Console.ReadLine());
n = Convert.ToInt16(Console.ReadLine());
int[,] A = new int[10, 10];
Console.Write("\nEnter matrix elements: ");
for (i = 0; i < m; i++) {
for (j = 0; j < n; j++) {
A[i, j] = Convert.ToInt16(Console.ReadLine());
}
}
Console.Clear();
Console.WriteLine("\nLower Triangular Matrix ");
for (i = 0; i < m; i++) {
for (j = 0; j < n; j++) {
Console.Write(A[i, j] + "\t");
}
Console.WriteLine();
}
for (i = 0; i < m; i++) {
Console.Write("\n");
for (j = 0; j < 3; j++) {
if (i >= j)
Console.Write(A[i, j] + "\t");
else
Console.Write("0\t");
}
}
Console.ReadLine();
}
}输出结果
Enter number of rows and columns of the matrix Enter matrix elements: Lower Triangular Matrix
