Purpose
Show mother wavelet or scaling function of the selected wavelet
Description
Wavelet functions are given by
where a denotes the scaling parameter that expands or shrinks the
wavelet signal along the t axis, setting the resolution of the wavelet, and
b is the translation parameter, representing the time-depencency of
the transform.
They are generated by a mother wavelet 
that meets the
condition
with 
being the Fourier transform of .
"Show wavelet" computes the mother wavelet or the scaling functions of the current wavelet using a cascade algorithm.
The parameters of "Show wavelet" are
- the option func that determines whether
- the "Scaling function" (0) or
- the "Mother Wavelet" (1)
is to be computed;
- the option (transtype) which gives the type of transform:
- "Analysis" (0) or
- "Synthesis" (1),
- number of octaves (n): number of steps for the cascade algorithm
