Linear Codes [HB 83]

New features:

• The advanced Zimmermann algorithm for minimum weight computation has been implemented.
• New functions MinimumWord and MinimumWords to return one word or all words, respectively, of minimum weight from a code.
• New function VerifyMinimumWeight to verify that a code has minimum weight at least d for given d.
• New function WordsOfBoundedWeight for computing words of bounded weight.
• New function DirectProduct to return the direct product of two codes.
• New function BCHBound to return the BCH bound for a cyclic code (a lower bound for the minimum weight).
• New code attributes MinimumWeightWord, MinimumWeightUpperBoundWord and MinimumWeightRows.
• Bugs in ExpurgateCode, and QRCode have been fixed. QRCode now returns the correct quadratic residue code!
