I use wavedec function to decompose input data and use detcoef to get detail coefficients, the problem is: If I have different length of input vectors, for example 1024 datapoints and 550000 datapoints, the detail coefficients will be different and I can't compare them directly because of the difference. Is there a proper method I can compare the detail coefficient of different input vectors.
