repetitionCode -- repetition code

Usage:

repetitionCode(F,n)
Inputs:
- F, a Galois field,
- n, an integer,
Outputs:
- an instance of the type LinearCode,

Description

Returns the repetition code over F of length n.

i1 : F = GF(2,3);

i2 : n=7;

i3 : C=repetitionCode(F,n);

i4 : C.ParityCheckMatrix

o4 = | 1 1 0 0 0 0 0 |
     | 1 0 1 0 0 0 0 |
     | 1 0 0 1 0 0 0 |
     | 1 0 0 0 1 0 0 |
     | 1 0 0 0 0 1 0 |
     | 1 0 0 0 0 0 1 |

             6      7
o4 : Matrix F  <-- F

Ways to use repetitionCode:

repetitionCode(GaloisField,ZZ)

For the programmer

The object repetitionCode is a method function.
