写一个矩阵乘法子程序时，出现如下错误

只看该作者 · 2014-12-5 21:05

MatrixMUL(float* A, int A_Row,int A_Col, float* B,int B_Row, int B_Col, float *Result)
{

  int i,j,k;
  float sum;

  if(A_Col == B_Row) // dimensions of matrixes must be accordance with each other
  {
   for( i = 0; i < A_Row; i++) // compute the first row of results
   {
         for(j = 0; j < B_Col; j++)
         {
            sum = 0.0f;
            for(k = 0; k < A_Col; k++)
            {
                  sum += (*(A + i*A_Col + k))*( *(B + k*B_Col + j));
                  //sum = sum + temp;
            }

            *(Result + i*B_Col + j) = sum;

         }
   }

  }

}

在一个工程里运行，出现如下错误，

"C:\Users\User\AppData\Local\Temp\0912810", ERROR! at line 754: [E0004] Illegal operand combination
         MACF32 R7H,R3H,*XAR0++,*XAR7 ; [CPU_] |146|

是什么原因？
