time-frequency representation.
signal in the time-domain.
time instants.
chosen representation (name of the corresponding sci-file)
visualization parameter vector : PARAM = [DISPLAY LINLOG THRESHOLD LEVNUMB NF2 LAYOUT FS ISGRID fmin fmax] where
1..5 for contour, imagesc, pcolor, surf or mesh
0/1 for linearly/logarithmically spaced levels
is the visualization threshold, in %
is the number of levels used with contour
is the number of frequency bins displayed
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
is the sampling frequency (may be set to 1.0)
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
smallest normalized frequency
highest normalized frequency
parameters of the representation. Run the file tfrparam(METHOD) to know the meaning of P1..P5.
tfrview allows to visualize a time-frequency representation. tfrview is called through tfrqview from any tfr* function.
