Kernel density estimates....group data into bin and KDE

Hi,

I'm a beginner in matlab and I need to make Kernel density estimate curves.

The only thing I have is one column with my data (e.g a txt file that I attach). What i would like to do is:

• make a KDE with these data. I think first i need to group my data into bins (right??). If that is the case, I would like bins from 0 to 8 at intervals of 0.5

Could you help me with the code?

Thank you

No, you don't need to make bins. This might give you a start:

Pressure = importdata('Pressure.txt');
kernest = fitdist(Pressure,'kernel');
x=0:0.1:5;
kernpdf = kernest.pdf(x);

histogram(Pressure,'Normalization','pdf')
hold on;
plot(x,kernpdf
