|
* \brief Array2D class representing a 2D array with size defined |
| 29 |
|
* at construction time. |
| 30 |
|
* |
| 31 |
|
* This class derives from the vnl_matrix<> class. |
| 32 |
|
* Its size is assigned at construction time (run time) and can not be |
| 33 |
|
* changed afterwards. |
| 34 |
|
* |
| 35 |
|
* The class is templated over the type of the elements. |

|
* |

* Template parameters for class Array2D: |
| 38 |
|
* |
| 39 |
|
* - TValueType = Element type stored at each location in the array. |
