Complex Morlet wavelet

`[`

returns the complex Morlet wavelet,
`psi`

,`x`

] = cmorwavf(`lb`

,`ub`

,`n`

)`psi`

, with time-decay
parameter, `fb`

, and center
frequency, `fc`

, both equal to 1.
The wavelet is evaluated on an
`n`

-point regular grid,
`x`

, for the interval
[`lb`

,`ub`

].
The general expression for the complex Morlet
wavelet is

$$\psi (x)=\frac{1}{\sqrt{\pi \cdot \text{fb}}}\mathrm{exp}(2\pi i\cdot \text{fc}\cdot x)\mathrm{exp}(-{x}^{2}/\text{fb}).$$
