WebOct 1, 2015 · The starting point is that the function you're dealing is linear in log-log space for small enough segments. One can then write the equation of the line at the segment endpoints: log ( y 1) = m 1 log ( x 1) + n 1. log ( y 2) = m 1 log ( x 2) + n 1. where m 1 is the slope of the line and n 1 is its y -intercept. WebNov 23, 2024 · Specifically, SciPy cumtrapz needs the initial=0 argument to match Matlab.
