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.
| 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
| 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
| 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
| 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
| 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
