Hello, IDL colleagues: I need to detect an abrupt change(s) in a signal series. The concept is similar to: "https://www.r-bloggers.com/a-simple-intro-to-bayesian-change-point-analysis/" or "https://de.mathworks.com/help/signal/ref/findchangepts.html". I cannot find any applicable IDL functions for my purpose. Does anyone have some comments or suggestions to me. Thanks a lot in advance. Best regards, Chia-Hsiang Yang
