GrayCodePosition

GrayCode(n::Integer) Represents the Gray code over n bits. n must be positive. GrayCode implements iteration to generate all codewords.

GrayCodePositions[{signed::Bool}](code::GrayCode)

Represents the sequence of transient indices of a Gray code. The ith transient index is the position of the bit of code[i] that is flipped to obtain code[i+1]. The entire sequence can be generated by iteration. The optional signed type parameter (default false) gives the signed transient sequence, a positive (negative) sign indicating the bit is set (reset).

Note: The returned transient indices are 1-based.

gray(n::Integer)

Compute the nth Gray codeword.

graytransient(n::Integer)

Compute the nth Gray code transient index, in 1-based indexing.

signedgraytransient(n::Integer)

Compute the nth signed Gray code transient index, in 1-based indexing.
