**Meyer Wavelet: meyr**

Both and are defined in the frequency domain, starting with an auxiliary function (see [Dau92] pages 117, 119, 137, 152). By typing `waveinfo('meyr')`

at the MATLAB command prompt, you can obtain a survey of the main properties of this wavelet.

The Meyer wavelet and scaling function are defined in the frequency domain:

- Wavelet function

- and

- where

- Scaling function

By changing the auxiliary function, you get a family of different wavelets. For the required properties of the auxiliary function (see References for more information). This wavelet ensures orthogonal analysis.

The function does not have finite support, but decreases to 0 when , faster than any inverse polynomial

- such that

This property holds also for the derivatives:

The wavelet is infinitely differentiable.
