MATRIX("CIRCULANT",order)
- is the order of the arrowhead matrix.
is the order of the arrowhead matrix.Description
- This function gives the Circulant matrices of given order.
- A circulant matrix is a special kind of Toeplitz matrix where each row vector is rotated one element to the right relative to the preceding row vector.
- An n × n circulant matrix is formed from any n vector by cyclically permuting the entries.
- Starting with [a b c] we can generate the 3 × 3 circulant matrix
C =\begin{vmatrix} a & b & c \\ c & a & b \\ b & c & a \\ \end{vmatrix}
- Here MATRIX("circulant") is giving the circulant matrix for random numbers in decimal.
8Circulant matrices are very useful in digital image processing, and the n×n circulant matrix is implemented as CirculantMatrix.
