Examples

• Creating arrays and accessing elements:
  `

#include "tnt.h"
using namespace TNT;
Array2D< double > A(M,N, 0.0); /* create MxN array; all zeros /
for (i=0; i < M; i++)
for (j=0; j < N; j++)
A[i][j] = f(i,j); /* initalize array values */
Array2D< double > B = A.copy(); / create a new copy /
Array2D< double > C(B); / create a new view of B /
/ Both arrays (B & C) share data */
`

• Declarations
  Array2D< double > A; /* initalize null (empty) array /
  Array2D< double > B(M,N); / create an MxN array; uninitalized*/
  Array2D< double > C(M,N) = 0.0; /* create an MxN array; all zeros */
• Assignments
  A[i][j] = 3.13; /* individual element assignment /
  A = B; / shallow array assignment /
  A = B.copy(); / explicit array copy */
