Semiparametric model
Template:Distinguish In linear algebra, an alternant matrix, is a matrix with a particular structure, in which successive columns have a particular function applied to their entries. An alternant determinant is the determinant of an alternant matrix. Such a matrix of size m × n matrix may be written out as
or more succinctly
for all indices i and j. (Some authors use the transpose of the above matrix.)
Examples of alternant matrices include Vandermonde matrices, for which and Moore matrices for which .
If and the functions are all polynomials we have some additional results: if for any then the determinant of any alternant matrix is zero (as a row is then repeated), thus divides the determinant for all . As such, if we take
(a Vandermonde matrix) then divides such polynomial alternant determinants. The ratio is called a bialternant. In the case where each function , this forms the classical definition of the Schur polynomials.
Alternant matrices are used in coding theory in the construction of alternant codes.
