PLOTNSDGT Plot non-stationary Gabor coefficients
Usage: plotnsdgt(c,a,fs,dynrange);
Input parameters:
coef : Cell array of coefficients.
a : Vector of time positions of windows.
fs : signal sample rate in Hz (optional)
dynrange : Color scale dynamic range in dB (optional).
PLOTNSDGT(coef,a) plots coefficients computed using NSDGT or
UNSDGT. For more details on the format of the variables coef and a,
please read the function help for these functions.
PLOTNSDGT(coef,a,fs) does the same assuming a sampling rate of
fs Hz of the original signal.
PLOTNSDGT(coef,a,fs,dynrange) additionally limits the dynamic range.
C=PLOTNSDGT(...) returns the processed image data used in the
plotting. Inputting this data directly to imagesc or similar
functions will create the plot. This is useful for custom
post-processing of the image data.
PLOTNSDGT supports all the optional parameters of TFPLOT. Please
see the help of TFPLOT for an exhaustive list. In addition, the
following parameters may be specified:
'xres',xres Approximate number of pixels along x-axis / time.
The default value is 800
'yres',yres Approximate number of pixels along y-axis / frequency
The default value is 600
