Peak finding and measurement, 2019
A set of fast customizable functions for locating and measuring the peaks in noisy time-series signals. Adjustable parameters allow discrimination of "real" signal peaks from noise and background. Determines the position, height, and width of each peak by least-squares curve-fitting. It can find and count over 10,000 peaks per second, and find and measure 1800 peaks per second, in very large signals. Includes two interactive versions, one with mouse-controlled sliders and one with keyboard control, for adjusting the peak finding criteria in real-time. Self-contained demos show how it works.
