Hi,
I am trying to plot the histogram along with pdf. I am already having the script for histogram, could someone please help me to implement pdf in the below script.
histogram(Output,'Normalization', 'probability','FaceColor','black');
saveas(gcf, sprintf('Histogram.bmp'))
savefig(gcf, sprintf('Histogram'))

Hi,
With this I am just getting only histograms again. Actually, I would like to plot the histogram and distribution on the same plot.

The empirical distribution is what you get from the above command.
In order to get a proper distribution curve, you will have to tell MATLAB which underlying distribution your measurement data follow and determine the parameters of this distribution (e.g. using MATLAB's "mle").
Look at the example
