hsvd_vec: HSVD of a complex vector.

In spant: MR Spectroscopy Analysis Tools

HSVD of a complex vector.

Description

HSVD method as described in: Barkhuijsen H, de Beer R, van Ormondt D. Improved algorithm for noniterative and timedomain model fitting to exponentially damped magnetic resonance signals. J Magn Reson 1987;73:553-557.

Usage

hsvd_vec(y, fs, comps = 40, irlba = TRUE, max_damp = 0)

Arguments

y	time domain signal to be filtered as a vector.
fs	sampling frequency of y.
comps	number of Lorentzian components to use for modelling.
irlba	option to use irlba SVD (logical).
max_damp	maximum allowable damping factor. Default value of 0 ensures resultant model is damped.

Value

basis matrix and signal table.
