## Abstract In this paper, the multifrontal method is employed to precondition the conjugate gradient (CG) algorithm with the block Toeplitz matrix based fast Fourier transform (FFT) technique for dense matrix equations from the mixed potential integral equation (MPIE) to enhance the computational

## Abstract A new __O__(__N__ log __N__) FFT‐based method to expedite matrix–vector multiplies involving multilevel block‐Toeplitz (MBT) matrices is presented. The method is also a minimal memory method with __O__(__N__) memory requirements because only nonredundant entries of the MBT matrix are st
