Thread: When two waves are identical?

    When two waves are identical?

    Imagine a simple sin wave. Then strech/compress it on one or more intervals of the x axis.
    My question is: which mathematical branch should I use to say that the second wave is identical to the first?

    It's a signal processing problem: I need to categorize waves even if *parts* of a wave have a different temporal scale
