Creates symmetric and asymmetric Toeplitz matrices.
toeplitz.spam(x, y = NULL, eps = .Spam$eps)
the first row to form the Toeplitz matrix.
for asymmetric Toeplitz matrices, this contains the first column.
A tolerance parameter: elements of x such that abs(x) <= eps set to zero. Defaults to eps = .Spam$eps.
x
abs(x) <= eps
eps = .Spam$eps
The Toeplitz matrix in spam format.

The vector y has to be of the same length as x and its first element is discarded.
