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.

#include <Array2.h>

Inherited by Matrix_< T >.
