该程序利用linux下多进程编程实现矩阵的乘法，提过运算的速度-Under the program using linux multi-process programming matrix multiplication, mentioned the speed of operation

Linux下利用多线程实现矩阵相乘的并行计算-Linux using multi-threaded parallel computing for matrix multiplication

在Linux下分别用Ptread线程和一般的方法编矩阵乘法，比较两者的差异。-we use Pthread and the general method to implement the matrix multiplication,and compare the difference between the two methods.
