mvmul.c

C语言实现的矩阵的常用计算！包括：矩阵乘法

void      MVmul(
				Matrix a,
				Vector b,
				Vector c,
				int    m,
				int    r,
				int    n)
{
          int      i,j;
		  double   sum;
		  
          if((m>0)&&(n>0)&&(r==n))
		  {
			   for(i=0;i<m;i++)
			   {     sum=0.0;
			         for(j=0;j<r;j++)
					     sum+=a[i][j]*b[j];
					 c[i]=sum;
			   }
		  }
		  else
		  {
		       printf("The multiplication of the Matrix and Vector is error!\n");
		  }
}
