Dear All, I need to know how to detect discontinuities in a series of discrete set of values. For example, if I have the following series: 1, 2, 3, 10, 5, 6... Then there is a discontinuity at the 4th item. Or if I have this series: 1, 4, 9, 100, 25, 36... Then also there is a discontinuity at the 4th item. I tried the MATLAB wavelet toolbox that detect discontinuities but for continuous signals and not for discrete sets. So, I need to find the discontinuity for any series. If there is an option in wavelets to do this or anyone has done this before, please reply as soon as possible. Thank you in advance.
