quemb.shared.helper.ravel_symmetric

quemb.shared.helper.ravel_symmetric(a, b)

Flatten the index a, b assuming symmetry.

The resulting indexation for a matrix looks like this:

0
1   2
3   4   5
6   7   8   9

Parameters:

• a (TypeVar(_T_Integral, bound= int | integer))

• b (TypeVar(_T_Integral, bound= int | integer))

Return type:

TypeVar(_T_Integral, bound= int | integer)
