Matlab has a function " ksdensity " that does it, but honestly I have never used it. Or if you are familiar with R, you can use it too.

I have bunch of scalar data and I need to sketch the PDF of it. I am familiar with "hist" and "bar" functions in Matlab where basically you create some bins and put the data in there. However, I would want to draw only a curve that represent pdf and do not need the "bars"...In other words, I need to draw a curvilinear line that joins the top of these bars (in some sense)...Any idea on this would be much appreciated. any Matlab function? To clarify what I mean, I also attached a jpg image (I want the form on the left not on the right in that picture) Bests, Hatef -------------- Hatef Monajemi PhD Student Environmental Fluid Mechanics and Hydrology Department of Civil and Environmental Engineering Stanford University 473 Via Ortega, Y2E2 Bldg, Room M25 Stanford, CA 94305 Email: [email protected] Web: http://www.stanford.edu/~monajemi/ -- Mailing list: https://launchpad.net/~stanford-imaging Post to : [email protected] Unsubscribe : https://launchpad.net/~stanford-imaging More help : https://help.launchpad.net/ListHelp -- Xiaoyi Liu Department of Civil and Environmental Engineering Stanford University EFML 161, Yang & Yamasaki Environment & Energy Building - 4020 473 Via Ortega Stanford, CA 94305 www.stanford.edu/~shawnliu
