I have two signals generated by timeseries. I would like to compare them and get the signal result. I use the C=max(A,B) but I got errors

Error using timeseries/utStatCalculation (line 45) A specified property is missing a corresponding value.

Error in timeseries/max (line 25) out = utStatCalculation(this,'max',varargin{:});

Error in test_signal_C (line 17)

What function should I use to calculate the max?

Maybe C=max(A.Data,B.Data)? You problem definition is a little vague, what exactly are you trying to find?

Use comment instead of a new answer.

You can find the indices that correspond to the maximum values using:

[M,Index] = max()

Then access A.Time(Index) to find the time.

I try to find the maximum value comparing two ramp signals. I have implement your suggestion but I have problems with times.
