Abstract: Conventional full waveform inversion (FWI) requires explicit computation of adjoint source backpropagated wavefields and derivation of adjoint equations to obtain the gradient of the ...

Abstract: The inversion of Toeplitz matrices plays a vital role in time series forecasting, structured covariance estimation in machine learning and signal processing. Traditional methods, including ...

ABSTRACT: In this paper we present and test a numerical method for computing eigenvalues of 4th order Sturm-Liouville (SL) differential operators on finite intervals with regular boundary conditions.
