I need to get empirical data for a PDF function. I tried using a ksdensity function but it only plotted 100 points. Is there any way to increase the amount of data points in the ksdensity function? Or is there another way to get empirical data? For context I need to get the x and y data points of the final plot. Using get(plot,'Xdata') or something like that. I appreciate any help!

Hi Bret,
what do you mean by "empirical data". Are you looking for a draw of numbers that is e.g. normally distributed? In this case
doc normrnd
Or are you interested in plotting the PDF? In this case take a look at
doc normpdf
Both are from Statistics and Machine Learning Toolbox.

I was using normal distributions unfortunately my team leader wants the exact data and not a modified distribution.

I don't understand. What are exact data? You can edit the normpdf function to see how it's computed ...
