Hi,
i am trying to add a time vector to the spectrum using this scrupt but i cannot do it
Could somebody please help me?
thank you very much in advance!
fs=500
timeLimits = [1 28513];%
endtime = 28513/fs;
Time2 = 0:1/fs:endtime
frequencyLimits = [0 1]; % Normalized frequency (*pi rad/sample)
overlapPercent = 50;
%% compute
Diametre_R2_detrend_ROI = Diametre_R2_detrend(:);
Diametre_R2_detrend_ROI = Diametre_R2_detrend_ROI(timeLimits(1):timeLimits(2));
[P,F,T] = pspectrum(Diametre_R2_detrend_ROI, ...
'spectrogram', ...
'FrequencyLimits',frequencyLimits, ...
'OverlapPercent',overlapPercent);

It is not possible to run that (missing data), and nearly impossible to determine what you want to do.
It is certainly possible to use a time vector as an argument to pspectrum. See t in the Input Arguments documentation section.
