Element access
|
||
|
==================================
|
||
|
|
||
|
The elements of the arrays can be naturally accessed using the ( ) operator.
|
||
|
|
||
|
If A is an array<T,R> and i,j,k, its indices
|
||
|
|
||
|
A(i,j,k) is the element (i,j,k) of the array.
|

.. compileblock::

#include <triqs/arrays.hpp>

namespace tqa=triqs::arrays;
|
||
|
int main(){
|
||
|
tqa::array<double,2> A(2,3);
|
||
|
A() = 0; // assign 0 to a complete view of A.
|
||
|
A(0,0) = 5;
|
||
|
A(1,1) = 2* A(0,0);
|
||
|
std::cout <<"A = "<< A << std::endl;
