# what is matrix : each row vector is rotated two(and more such $k$) element to the right relative to the preceding row vector?

In linear algebra, if each row vector is rotated one element to the right relative to the preceding row vector,we call this matrix is a circulant matrix (is a special kind of Toeplitz matrix) http://en.wikipedia.org/wiki/Circulant_matrix

My question: if each row vector is rotated two(and more such $k$) element to the right relative to the preceding row vector, this matrix have name? and this case have some paper to research it?

Thank you very much!
