quemb.shared.helper.ravel_Fortran

quemb.shared.helper.ravel_Fortran(a, b, n_rows)

Flatten the index a, b assuming column-mayor/Fortran indexing

The resulting indexation for a 3 by 4 matrix looks like this:

0   3   6   9
1   4   7  10
2   5   8  11

Parameters:

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

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

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

Return type:

TypeVar(_T_Integral, bound= int | integer)
