However, when you flip it around, the second vector sticks out in sequence space at points where the other function is not defined (and vice versa). Other MathWorks country In this example, the input signal is a few cycles of a sine wave plus a slowly rising ramp. People dont always realize the value of a second opinion or of finding doctors with superior outcomes. A good example is the problem of removing echoes from acoustic signals.
