Abstract
In this paper, several infinite families of near MDS codes with dimension four are constructed with special matrixes and oval polynomials. The weight enumerators of them are explicitly determined. As an application, the duals of these near NMDS codes are proved to be both distance-optimal and dimension-optimal locally recoverable codes.
