浅谈mwArray和一般数组的区别

可以用下面的代码详细理解mwArray和一般数组之间的区别

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

mwArray a(3, 2, mxDOUBLE_CLASS);   double *aData;   aData = new double[6];   int iii;   for( iii=0; iii<6; ++iii)   {     aData[iii] = iii+1;   }   // print output   std::cout << "a = " << std::endl;   std::cout << aData[0] << ",\t" << aData[1] << std::endl;   std::cout << aData[2] << ",\t" << aData[3] << std::endl;   std::cout << aData[4] << ",\t" << aData[5] << std::endl;      a.SetData(aData, 6);   std::cout << "a(1,1)="<<a(1,1)<<std::endl;   std::cout << "a(1,2)="<<a(1,2)<<std::endl;   std::cout << "a(2,1)="<<a(2,1)<<std::endl;   std::cout << "a(2,2)="<<a(2,2)<<std::endl;   std::cout << "a(3,1)="<<a(3,1)<<std::endl;   std::cout << "a(3,2)="<<a(3,2)<<std::endl;

运行结果如图：【一位数组到多维数组的组织方式是列优先的】

?

1 2 3 4 5 6 7 8 9 10

a = 1,  2 3,  4 5,  6 a(1,1)=1 a(1,2)=4 a(2,1)=2 a(2,2)=5 a(3,1)=3 a(3,2)=6
