PHASEUNLOCK - Undo phase lock of Gabor coefficients

Usage

c=phaseunlock(c,a);

Description

phaseunlock(c,a) removes phase locking from the Gabor coefficients c. The coefficient must have been obtained from a dgt with parameter a.

Phase locking the coefficients modifies them so as if they were obtained from a time-invariant Gabor system. A filter bank produces phase locked coefficients.
