[ X, psir] = gauferPub(N,W, NumWAW,NumWAW_max, Step) returns the fractional order derivative of
Gaussian wavelet, psir, on an N-point regular grid, X for the interval
[LB,UB].
This based on aproximated calculation algorithm by https://www.researchgate.net/publication/319534355
(Author: Can Evren Yarman )
USAGE example:
[x,psir] = gauferPub(300, 0.25,0,2.0,0.25);
plot(transpose(psir)); Where W is the reference cyclic
frequency W0 parameter. The above will generate a family of wavelets
from fractional order of 0 (Gaussian function) to 2 (Mexican Hat) step
0.25, i.e. 8 wavelets.
