Array2< T > Class Template Reference
Detailed Description
template<class T>
class asl::Array2< T >
A simple 2-dimensional dynamic array or matrix.
Array2<int> a(3, 3);
Array2<float> b = {
{ 1, 2, 3 },
{ 3, -1.5f, 0 }
};
b(1, 1) = 7.25f;
For mathematical matrices use class Matrix_ which support arithmetic operations and other functions.
