I am having trouble fitting the below bimodal data, which I plotted in a histogram. I am trying to do this as min_pts is a matrix. Maybe 'Kernel' is the way to go, but I am not sure how to do this is a matrix. Here are the x values: tvec = 0:.013653333:(.013653333*97); x = tvec(1:end-1);

min_pts =

1.0e-04 *

Hi Sophie

Is min_pts suppose to be a collection of data points for the same variable or three separate variables differentiated by the 3 columns? In addition are the x values the bin center values?
