A set of transformations.
Add a transformation.
| tr | transformation to add |
| const_iterator t_set::begin | ( | ) | const [inline] |
Begin, for iterating through the set.
| t_set& t_set::clear | ( | ) | [inline] |
Clear all transformations.
Remove all the transformations
Set transformations to their conjugates by a given transformation.
If the given transformation is M then each transformation T is set to MTM^-1.
| m | the transformation to form the conjugates with. |
| const_iterator t_set::end | ( | ) | const [inline] |
End, for iterating through the set.
| const set<mat3d>& t_set::get_trans | ( | ) | const [inline] |
Get the underlying transformation set.
return The underlying transformation set
| set<mat3d>& t_set::get_trans | ( | ) | [inline] |
Get the underlying transformation set.
return The underlying transformation set

Find the transformations that are common to both sets of transformations.
| s1 | one of the sets. |
| s2 | the other set. |
| bool t_set::is_set | ( | ) | const [inline] |
Check if there are transformations in the set.
true if set, otherwise false Form the left coset with a given transformation.
If the given transformation is M then each transformation T is set to MT in the coset.
| m | the transformation to form the left coset with. |
| t_set & t_set::min_set | ( | const t_set & | tr_whole, |

Set to direct product of two sets of transformations.
Each transformation of one set is combined with every transformation from the other set.
| s1 | one of the sets. |
| s2 | the other set. |
Set to direct product of current transformations with another set of transformations.
Each transformation of current set is combined with every transformation from the other set.
| s | the other set. |
