xspectrogram
Cross-spectrogram using short-time Fourier transforms
Syntax
Description
[___] = xspectrogram(___,
returns the cross-spectrogram over the frequency range specified by
freqrange
)freqrange
. Valid options for
freqrange
are 'onesided'
,
'twosided'
, and 'centered'
.
[___] = xspectrogram(___,
specifies additional options using name-value arguments. Options include the
minimum threshold and output time dimension.Name,Value
)
[___] = xspectrogram(___,
returns short-term cross power spectral density estimates if
spectrumtype
)spectrumtype
is specified as 'psd'
and returns short-term cross power spectrum estimates if
spectrumtype
is specified as
'power'
.
xspectrogram(___)
with no output arguments
plots the cross-spectrogram in the current figure window.
xspectrogram(___,
specifies the axis on which to plot the frequency. Specify
freqloc
)freqloc
as either 'xaxis'
or
'yaxis'
.
