lab1为多线程计算圆周率的程序 lab2为多线程计算矩阵乘法的程序 有实验报告和说明文档

package lab2;

public class Matrix {
	int r1 = 800;
	int c1 = 800;
	int r2 = 800;
	int c2 = 800;
	
	long m1[][] = new long[r1][c1];
	long m2[][] = new long[r2][c2];
	long r[][] = new long[r1][c2];
	
	Matrix() {
		int v1=0;
		int v2=1;
		for(int i=0;i<r1;i++) {
			for(int j=0;j<c1;j++)
			{
				m1[i][j] = v1;
				v1 = v1+2;
				m2[i][j] = v2;
				v2 = v2+2;
			}
