Description (last modified by )
As #19930 introduces a new encoder which computes a generator matrix for codes defined from their parity check matrices, it would be nice to update codes.LinearCodeFromCheckMatrix
.
It could be renamed, made a class, and thus use the encoder described above.

Replying to jfields:
Should the description for this ticket read "...computes a generator matrix for codes defined from their
generatorparity check matrices" ?
Yes, nice catch! I changed the description.

Hi David
Which encoder are you mentionning in the description of the ticket ?
Are you suggesting to use the encoder codes.encoders.LinearCodeParityCheckEncoder
?
This encoder is deprecated.

Actually, the point was to use the ParityCheckEncoder
to as a building brick
for some codes, instead of having LinearCodeFromCheckMatrix
But as you said, ParityCheckEncoder
is deprecated, and #21165 deprecates LinearCodeFromCheckMatrix
.
So, let's set this ticket to invalid/won't fix
.

Closing tickets in the sage-duplicate/invalid/wontfix module with positive_review (i.e. someone has confirmed they should be closed).
Should the description for this ticket read "...computes a generator matrix for codes defined from their
generatorparity check matrices" ?
