Each submatrix is either a zero matrix or a cyclically shifted version of a diagonal matrix. Data Types: double Output Arguments collapse all H — Parity-check matrix sparse logical matrix In mathematics, and in particular in group theory, a cyclic permutation (or cycle) is a permutation of the elements of some set X which maps the elements of some subset S of X to each other in a cyclic fashion, while fixing (that is, mapping to themselves) all other elements of X. If S has k elements, the cycle is called a k-cycle. Cycles are often denoted by the list of their elements enclosed with parentheses, in the order to which they are permuted.
