MATLAB : frequency distribution

Question

I have raw observations of 500 numeric values (ranging from 1 to 25000) in a text file, I wish to make a frequency distribution in MATLAB. I did try the histogram (hist), however I would prefer a frequency distribution curve than blocks and bars.

Any help is appreciated !

Answer 1

If you pass two output parameters to HIST, you will get both the x-axis and y-axis values. Then you can plot the data as you like. For instance,

[counts, bins] = hist(mydata);
plot(bins, counts); %# get a line plot of the histogram
