Hi all
I Have a given set of data points (around 600.000). i have used the polyfit function, to fit a 5. degree polynomial ( P_fit = polyfit(Z,X,5); ). And yes my Z and X axis has to be shifted. Now my question is, how do i find the maximum slope on the polynomial? I have searched around this forum and the web, but without any success...

You can get the derivative of the polynomial using the polyder command.
