tfrview

Visualization of time-frequency representations

Calling Sequence

tfrview(TFR, SIG, T, METHOD, PARAM)
tfrview(TFR, SIG, T, METHOD, PARAM, P1)
tfrview(TFR, SIG, T, METHOD, PARAM, P1, P2)
tfrview(TFR, SIG, T, METHOD, PARAM, P1, P2, P3)
tfrview(TFR, SIG, T, METHOD, PARAM, P1, P2, P3, P4)
tfrview(TFR, SIG, T, METHOD, PARAM, P1, P2, P3, P4, P5)

Parameters

TFR :

time-frequency representation.

SIG :

signal in the time-domain.

T :

time instants.

METHOD :

chosen representation (name of the corresponding sci-file)

PARAM :

visualization parameter vector : PARAM = [DISPLAY LINLOG THRESHOLD LEVNUMB NF2 LAYOUT FS ISGRID fmin fmax] where

DISPLAY :

1..5 for contour, imagesc, pcolor, surf or mesh

LINLOG :

0/1 for linearly/logarithmically spaced levels

THRESHOLD :

is the visualization threshold, in %

LEVELNUMB :

is the number of levels used with contour

NF2 :

is the number of frequency bins displayed

LAYOUT :

determines the layout of the figure : TFR alone (1), TFR and SIG (2), TFR and spectrum (3), TFR and SIG and spectrum (4), add 4 if you want a colorbar

FS :

is the sampling frequency (may be set to 1.0)

ISGRID :

depends on the grids' presence : isgrid=isgridsig+2*isgridspec+4*isgridtfr where isgridsig=1 if a grid is present on the signal and =0 if not, and so on

fmin :

smallest normalized frequency

fmax :

highest normalized frequency

P1..P5:

parameters of the representation. Run the file tfrparam(METHOD) to know the meaning of P1..P5.

Description

tfrview allows to visualize a time-frequency representation. tfrview is called through tfrqview from any tfr* function.
