Missing arithmetic functions for boost.units

[David Wright]

Hello Klaus,

I have found that and arithmetic functions such as min() max(), etc. don’t work with boost.units:

For example, this piece of code works:

    const blaze::DynamicVector<double> x(100);


    double max    = blaze::max(x);
    double min    = blaze::min(x);
    double mean   = blaze::mean(x);
    double stdDev = blaze::sqrt(blaze::mean(blaze::pow2(x - mean)));

‌

Whereas the same with boost.units does not:

    using unit = boost::units::quantity<boost::units::si::plane_angle>;

    const blaze::DynamicVector<unit> x(100, 1.0 * boost::units::si::radian);

    unit max    = blaze::max(x);
    unit min    = blaze::min(x);
    unit mean   = blaze::mean(x);
    unit stdDev = blaze::sqrt(blaze::mean(blaze::pow2(x - mean)));

Resulting in the following compile output:

Hi David!

Thanks again for reporting problems with Blaze. Luckily, this time all problems can be resolved rather easily:

• boost.units does not provide a min() and max() function. However, they provide a fmin() and fmax() function in <boost/units/cmath.hpp>. You can provide the according wrappers for them and use them in combination with blaze::reduce().
• In order to compute the standard deviation, please create a uniform vector from the mean value by means of blaze::uniform().

The following shows the complete code, which should compile and work flawlessly:

struct Fmin
{
   template< typename T1, typename T2 >
   constexpr decltype(auto) operator()( const T1& a, const T2& b ) const
   {
      return fmin( a, b );
   }
};


struct Fmax
{
   template< typename T1, typename T2 >
   constexpr decltype(auto) operator()( const T1& a, const T2& b ) const
   {
      return fmax( a, b );
   }
};

int main()
{
   using namespace boost::units;
   using unit = boost::units::quantity<boost::units::si::plane_angle>;

   const DynamicVector<unit> x{ 1.0 * si::radian, 2.0 * si::radian };

   const unit max    = blaze::reduce( x, Fmax{} );
   const unit min    = blaze::reduce( x, Fmin{} );
   const unit mean   = blaze::mean(x);
   const unit stddev = sqrt( blaze::mean( blaze::pow2( x - blaze::uniform(2,mean) ) ) );

   std::cerr << "\n"
             << "max    = " << max << "\n"
             << "min    = " << min << "\n"
             << "mean   = " << mean << "\n"
             << "stddev = " << stddev << "\n"
             << "\n";
}

On my machine this prints:

max    = 2 rad
min    = 1 rad
mean   = 1.5 rad
stddev = 0.5 rad

Does this solve the problem for you?

Best regards,

Klaus!

[David Wright]

Indeed this solves the problem perfectly! Thank you for your fantastic support once again, Klaus!

And have a nice weekend!

[Klaus Iglberger]

Hi David!

Thanks again for reporting this problem. It took some time and some refactoring, but now you’re able to use your original code without any problems. In case you encounter a similar problem, please feel free to report it again. Thanks,

Best regards,

Klaus!

[Klaus Iglberger]

Commits 6c663c8, ef010c5, e42ceb9 and 28719fa fix the compilation issue with the min(), max(), and mean() functions. The fix is immediately available via cloning the Blaze repository and will be officially released in Blaze 3.8.

[David Wright]

Hello Klaus,

thank you very much for your continuous effort! I was just trying out your latest changes (I pulled f7d985dd85) but I now seem to again run into similar problems with vector/scalar multiplication and division as you have resolved in a previous issue that I opened: #385.

Code producing the error:

            const boost::units::quantity<boost::units::si::length> bandwidth = 1.0 * boost::units::si::metre;
            const blaze::DynamicVector<boost::units::quantity<boost::units::si::length>> sample
                = {1.0 * boost::units::si::metre, 1.0 * boost::units::si::metre};
            const blaze::DynamicVector<boost::units::quantity<boost::units::si::dimensionless>> weights
                = sample / bandwidth;


            const double scale                                                                  = 1.0;

Hi David!

I apologize for the regression. Commit 119b90a fixes the compilation issues and you should now be able to cleanly compile all your examples.

Best regards,

Klaus!

[David Wright]

Hi Klaus,

no problem at all! Works perfectly now, thank you!

Best,

David
