The paper presents a method for computing \(p\) elements of the matrix \(TAS^T\) with an \((N,N)\)-Toeplitz (or Hankel) matrix \(A\) and Fourier- or cosine transform matrices \(T\), \(S\) in time \(O(p + N \log N)\) and with \(O(N)\) auxiliary storage followed by a brief discussion of applications.
