circulant {PBIBD}

This function generates circulant matrix of order n.

Description

Circulant matrix, which is a special kind of Toeplitz matrix, is a square matrix of order n whose rows are obtained by cyclically rotated versions of a list “l” of length n such that the first row is obtained by cyclically rotating one element toward right the list “l” and each of the other row is the cyclically rotated one element toward the right version of the previous row. This function is used to generate a circulant matrix of order n. The order of the circulant matrix i.e. n is supplied as an argument to the function.

Usage

circulant(n)

Arguments

n

n is the order of the circulant matrix we want to generate.

Value

The function returns a circulant matrix c of order n.
