Symmetric Matrix Resize

MTL version: mtl-2.1.2-23.tenative
Compiler: g++ (GCC) 4.1.2 20070925 (Red Hat 4.1.2-27)
Platform: Fedora 7 x86_64

I'm trying to resize a symmetric matrix using a simple test jig called =

SymmetricPackedResize.cpp ...

#include <mtl/mtl.h>

int main()
{
   typedef mtl::matrix<
     double,
     mtl::symmetric<mtl::lower>,
     mtl::packed<> >::type TDSymmetricMatrix;

   TDSymmetricMatrix Symmetric(6, 6);

   Symmetric.resize(16, 16);

   return 0;
}

I'm compiling with

g++ -IPathToMtlHeaders SymmetricPackedResize.cpp

The first set of errors I receive follow.  I've tried to separate them =

onto different lines for readability:

mtl-2.1.2-23/mtl/dense2D.h: In member function =91void mtl::dense2D<T, =

So the packed_offset class has the dim data member declared private. =

Looking at the rect_offset class for which resize actually works, there =

is a suspicious commenting out for the private: scope qualifier ahead of =

the data members.

I could do the same in packed_offset, but this would still leave me with =

the "packed_offset<...> has no member named ld.  It looks like resize =

will only work for rect_offset storage.

Does anyone see a workaround for this?

Peter, does version 4 deal with this?

How do I become an alpha tester of version 4?

Pete
