Hallo,

I need to allocate higher order arrays in OF, like 3D, 4D large matrices. I couldn't find any native OF class that do that. For 1D arrays I am using PtrList. In the case of 3rd order array, is it possible to use?:

PtrList<PtrList<PtrList<scalar>>>> array;
array.setSize[sizeX];
forAll(array, i)
{
    array[i].setSize[sizeY];
    forAll(array[i], j)
    {
        array[i][j].setSize[sizeZ];
    }
}

Is this safe in terms of memory leak? The member function PtrList::set would act funny, wouldn't it?

Or should I ratter allocate in a standard way?

scalar*** array;
array = new scalar**[sizeX];
for(int i = 0; i < sizeX; ++i)
{
     array[i] = new scalar*[sizeY];
     for(int j = 0; j < sizeY; ++j)
     {
          array[i][j] = new scalar[sizeZ];
     }
}

Then deallocate the array within delete loop in the class destructor.

How would you rather do that?

Best regards,
Rudolf
