Detailed Description

template<class T, unsigned N = 0>
class mth::Vector< T, N >

compile-time (static) vector of size N

This class endows Array<T,N> with the standard mathematical properties of a linear algebra vector. The vector is templated on scalar type so that math can be performed for a variety of (meaningful) scalar types.

Constructor & Destructor Documentation

Vector()

template<class T , unsigned N = 0>

mth::Vector< T, N >::Vector ( unsigned  n )

inline

construct with n elems

A dummy constructor Vector(n) is provided so that dynamic and static vectors can be used interchangebly

Definition at line 37 of file mthVector.h.

{(void)n;}

Member Function Documentation

operator()()

template<class T , unsigned N = 0>

T& mth::Vector< T, N >::operator() ( unsigned  i )

inline

mutable index operator

An index operator (i) is provided so that mth::Vector and mth::Matrix share a common index operator

Definition at line 47 of file mthVector.h.

{return (*this)[i];}

operator*() [1/2]

template<class T , unsigned N = 0>

Vector<T,N> mth::Vector< T, N >::operator* ( T const &  s ) const

inline

multiply a vector times a scalar

currently there is no scalar times vector operator, so do be sure to put scalar on the right hand side

Definition at line 84 of file mthVector.h.

    {
      Vector<T,N> r;
       for (unsigned i=0; i < N; ++i)
         r[i] = (*this)[i] * s;
       return r;
    }

operator*() [2/2]

template<class T , unsigned N = 0>

T mth::Vector< T, N >::operator* ( Vector< T, N > const &  b ) const

inline

vector dot product

we chose the default vector-vector multiplication operator to be the dot product. so far this seems to have been a good choice

Definition at line 104 of file mthVector.h.

    {
      T r = (T)0.0;
      for (unsigned i=0; i < N; ++i)
        r += (*this)[i] * b[i];
      return r;
    }

operator/()

template<class T , unsigned N = 0>

Vector<T,N> mth::Vector< T, N >::operator/ ( T const &  s ) const

inline

divide a vector by a scalar

equivalent to scaling by 1/s

Definition at line 93 of file mthVector.h.

    {
      Vector<T,N> r;
       for (unsigned i=0; i < N; ++i)
         r[i] = (*this)[i] / s;
       return r;
    }
