how to find the inflection point of a curve in matlab First use the sgolayfilt function to eliminiate as much of the noise as possible since taking the derivative will amplify it The use the gradient function to calculate the
To find inflection points of f solve the equation h 0 For this equation the symbolic solver returns a complicated result even if you use the MaxDegree option The idea is to work in 2 steps First define what is the noise level and simplify the x y polygonal line to some smooth subset xs ys After the simplification every change in
