mio::Array2D< T > Class Template Reference
Data classes

Detailed Description

template<class T>
class mio::Array2D< T >

The template class Array2D is a 2D Array (Matrix) able to hold any type of object as datatype. It relies on the Array2DProxy class to provide the [][] operator (slower than the (i,j) call). If the compilation flag NOSAFECHECKS is used, bounds check is turned off (leading to increased performances).
