Basics
Each Index type has multiple constructors, but all have the same pattern. For example, the
IndexDouble3 constructors are:
// Default constructor
IndexDouble3 idx_double_1 = new IndexDouble3();
// Copy constructor
IndexDouble3 idx_double_2 = new IndexDouble3(idx_double_1);
// Construct from I, J, K values
IndexDouble3 idx_dobule_3 = new IndexDouble3(3.0, 5.0, 7.0);
// I = 3.0, J = 5.0, K = 7.0
All Index types support the same operators. The results of the various operations are listed
using the following IndexDouble definitions as an example.
double i1 = 3.0 ;
double j1 = 5.0 ;
double k1 = 7.0 ;
double i2 = 9.0 ;
double j2 = 13.0 ;
double k2 = 17.0 ;
IndexDouble3 idx_double_1 = new IndexDouble3(i1, j1, k1);
// Value for idx_double_1 is (3.0, 5.0, 7.0)
IndexDouble3 idx_double_2 = new IndexDouble3(i2, j2, k2);
// Value for idx_double_2 is (9.0, 13.0, 17.0)
+ (addition)
IndexDouble3 idx_add_idx = idx_double_1 + idx_double_2;
// Value for idx_add_idx is (12.0, 18.0, 24.0)
IndexDouble3 idx_add_double = idx_double_1 + 5.0;
// Value for idx_add_double is (8.0, 10.0, 12.0) from 3+5, 5+5, 7+5
IndexDouble3 double_add_idx = 5.0 + idx_double_1;
// Value for idx_add_int is (8.0, 10.0, 12.0) from 5+3, 5+5, 5+7
