For an asymmetric matrix,the zero-nonzero pattern P of entries can be described by a digraphΓ(P)which has an arc if an entry is nonzero.The minimum rank of a z
In this paper, several usually used polynomial interpolation methods are explained in view of vector basis and dimension in linearalgebra theory. Using transiti
