Detect abrupt changes in signals with functions "wavedec" and/or "cwt"
1 view (last 30 days)
Hi, I read a MATLAB article called "Detecting Discontinuities and Breakdown Points", where both the wavedec (1-D wavelet decomposition) and detcoef (1-D detail coefficients) functions are used to detect abrupt changes of signals. I also checked the cwt (Continuous 1-D wavelet transform) function that might be used to detect abrupt changes of signals (right?). But something is not clear to me - Anyone who is able to reply to one of my two questions? :)
