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】

a =

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