IFILTERBANK Filter bank inversion
Usage: f=ifilterbank(c,g,a);
IFILTERBANK(c,g,a) synthesizes a signal f from the coefficients c*
using the filters stored in g for a channel subsampling rate of a (the
hop-size). The coefficients has to be in the format returned by
either FILTERBANK or UFILTERBANK.
The filter format for g is the same as for FILTERBANK.
If perfect reconstruction is desired, the filters must be the duals
of the filters used to generate the coefficients. See the help on
FILTERBANKDUAL.
