Complex Mexican hat wavelet
text:
In applied mathematics, the complex Mexican hat wavelet is a low-oscillation, complex-valued, wavelet for the continuous wavelet transform. This wavelet is formulated in terms of its Fourier transform as the Hilbert analytic signal of the conventional Mexican hat wavelet: Temporally, this wavelet can be expressed in terms of the error function,
as: This wavelet has O asymptotic temporal decay in | Ψ | ,
dominated by the discontinuity of the second derivative of Ψ ^ at ω = 0 . This wavelet was pr
