Issues with boost.units when trying to calculate the absolute value of a vector

Issue #357 resolved
David Wright created an issue

Hello,

I am trying to implement the MeanShift algorithm with blaze and boost.units. Everything has been working fine so far for basic matrix/vector operations, but I have just stumbled across a problem with calculating the norm of a boost.units based vector.

I the issue is with the following lines (simplified for debugging purposes):

    blaze::StaticVector<boost::units::quantity<boost::units::si::length, double>, 2, blaze::columnVector> vec(
        {1.0 * boost::units::si::metre, 1.0 * boost::units::si::metre});
    const auto abs = blaze::norm(vec);

‌

The Error output is as follows:

    Hi David!

    Thanks a lot for creating this defect report. You are correct, the norm calculation does not yet work flawlessly with Blaze. We apologize for the inconvenience and promise to resolve this issue as quickly as possible. For now, please use the following expression to compute the norm:

    const auto norm = root<2>( trans(vec)*vec );

    Again, thanks for creating this defect report,

    Best regards,

    Klaus!

    Hi David!

    Commit 06fed49 fixes the internal return type evaluation of the dense vector norm() computation. Unfortunately this is not enough: boost.units does not provide a sqrt() function for the computation of the square root, but instead provides a root() function. Since Blaze assumes a sqrt() function for all types, it is necessary to overload sqrt() for the boost::units::quantity class template:

    namespace boost {
namespace units {

template< typename T >
decltype(auto) sqrt( const quantity<T>& q )
{
   return root<2>( q );
}

} // namespace units
} // namespace boost

    With this the norm() computation works flawlessly. Again, thanks for creating this defect report,

    Best regards,

    Klaus!

  5. Klaus Iglberger

    Commit 06fed49 fixes the return type evaluation of the dense vector norm expressions. The fix is immediately available via cloning the Blaze repository and will be officially released in Blaze 3.8.

    Hi Klaus,

    thank you for your prompt response and resolution! I just pulled the latest master and will see if everything works. Also I found that boost.units provides a function sqrt in boost/units/cmath.hpp.

    ‌

    Best,

    David

    Thanks for the information that boost.units provides a sqrt() function. I didn't explicitly search for it since the documentation said that it instead provides a root() function. That information will prove to be useful. Thanks again!
