Hello,
I have a set of data representing current as a function of angles as shown in the attached figure. The data sets I have are not Gaussian and I would like to find the 95% area under the curve along with the x1 and x2 position to add to the plot, but I do not have the stat or curve fit toolbox. How can I do this in Matlab?
Thanks

Without your data, I can only outline the approach I would use. First, use the cumtrapz function to do the integration. Normalise the area to 1 by dividing the result of your cumtrapz call by the last value of the vector. Then use the interp1 function to calculate the value of the 2.5% and 97.5% values. Those will be the limits of the central 95%.
