New Results on Extended Intuitionistic Fuzzy Index Matrices

The Index Matrix (IM) is an extension of the ordinary matrix with indexed rows and columns. Over IMs, all standard matrix operations are defined and a lot of other ones that do not exist in the standard case. Intuitionistic Fuzzy IM (IFIM) is a modification of the IM the elements of which are Intuitionistic Fuzzy Pairs (IFPs). Extended IFIMs (EIFIMs) are IFIMs whose indices of the rows and columns are evaluated by IFPs. Over IMs, IFIMs and EIFIMs, a lot of operations, relations and operators are defined. In the present paper, some new operations, relations and operators, specific for EIFIMs, are introduced.
