I faced this problem when was constructing a coiflet
f(x)=#[h(k)*f(2*x-k)]
where f(x) is a scaling function
# is a sum from k=0 to 3*M-1
M is the number of vanishing moments
The question is :
Can coefficients h(k) be complex ??
If it is the case then what does it mean and
how can I use the Fast Wavelet Transform ??

please reply to alanbor@mailru.com
thank you
