VDMFEC implements Block ECC using a Forward Error Correction

(FEC) code based on Vandermonde (VDM) matrices in GF(2^8) due

to Luigi Rizzo. Given the FEC parameters K and N, with N

greater than K, N blocks are written for every K input blocks

in such a way that any K blocks are sufficient to reconstruct

the data. That is, up to N - K blocks out of every group of N

blocks may be lost without loss of data. Its primary

application is intended to be in recovering data from

unreliable media such as diskettes.
