I am a newcommer to GAP and am interested in the GUAVA
package as I am doing some research in Coding Theory. However
I have had big problems in getting the command 'GoppaCode' to
work. I have followed the GAP manual very closely and given the
x:=Indeterminate(GF(2),"x"); G:=x^2+x+1; L:=Elements(GF(8)); G:=GoppaCode(G,L);
Then I get the following error message----
'Error, no method found. For debugging hints type ..............
Error no first choice method found for 'CoefficientsRing' on 1
argument at Error(no_method_found)
CoefficientsRing(DefaultRing(p)) called from Codeword(x^(i-1) mod
temp, m+1) called from
VerticaConversionFieldMat(M,DefaultField(Flat(M))) called from
List([L,function(j), return j^i/value(GP(j);end);end)) called from
<<functions><arguments> called from read-eval-loop
Entering break read-eval-print loop ....
I have also tried other ways of defining L and G but to no avail. I
have also tried the AlternantCode command but again the same
Can anyone help and get me started.
Would be most grateful.
