MORSEDERIV Frequency-domain derivatives of generalized Morse wavelets. DCELL=MORSEDERIV(N,GAMMA,BETA,OMEGA) returns the first N normalized frequency derivatives of the lowest-order generalized Morse wavelet specified by parameters GAMMA and BETA, at the radian frequency OMEGA. DCELL is a cell array with DCELL{N} containing the Nth derivative. This derivative is defined as dn = ( omega^n / psi ) * ( d^n psi / d omega^n ) where omega is the radian frequency and psi is the wavelet. N must be a scalar. The other input parameters must either be matrices of the same size, or some may be matrices and the others scalars. DCELL=MORSEDERIV(N,GAMMA,BETA) evaluates the derivative at the peak frequency by default. For details see Lilly and Olhede (2009). Higher-order properties of analytic wavelets. IEEE Trans. Sig.
