Inverse fast Mellin transform.
X=iffmt(MELLIN,BETA) X=iffmt(MELLIN,BETA,M)
Mellin transform to be inverted. Mellin must have been obtained from FMT with frequency running from FMIN to 0.5 Hz.
Mellin variable issued from FMT.
number of points of the inverse Mellin transform. (default : length(MELLIN)).
inverse Mellin transform with M points in time.
iffmt computes the inverse fast Mellin transform of MELLIN. WARNING : the inverse of the Mellin transform is correct only if the Mellin transform has been computed from FMIN to 0.5 Hz, and if the original signal is analytic.
