关于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

         mwArray a(, ,  mxDOUBLE_CLASS);
         double *aData;
         aData = new double[];
         int iii;
         for( iii=; iii<; ++iii)
         {
                 aData[iii] = iii+;
         }
         // print output
         std::cout << "a = " << std::endl;
         std::cout << aData[] << ",\t" << aData[] << std::endl;
         std::cout << aData[] << ",\t" << aData[] << std::endl;
         std::cout << aData[] << ",\t" << aData[] << std::endl;  

         a.SetData(aData, );
         std::cout << "a(1,1)="<<a(,)<<std::endl;
         std::cout << "a(1,2)="<<a(,)<<std::endl;
         std::cout << "a(2,1)="<<a(,)<<std::endl;
         std::cout << "a(2,2)="<<a(,)<<std::endl;
         std::cout << "a(3,1)="<<a(,)<<std::endl;
         std::cout << "a(3,2)="<<a(,)<<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】

 a =
 ,
 ,
 ,
 a(,)=
 a(,)=
 a(,)=
 a(,)=
 a(,)=
 a(,)=
