Hi everybody, i have some random numbers and i would like to know what is the distribution associated with it ? Is it possible to represent it to know the density of probabilities of it ?
thanks :)

There are so many distributions that you have to make some choices. First, look at the distribution of your numbers and, by sheer logic, select a few candidates (beta, poisson, normal, ...). Then try to fit them.

For the actual distribution, use histogram():
histObject = histogram(yourData(:));
You can also use hist(), histc(), histcounts(), or imhist() depending on exactly what you want to do.
For a theoretical fit, use fitdist(), if you have the Statistics and Machine Learning Toolbox and you know the distribution you want to fit your data to. From the help:
pd = fitdist(x,distname) creates a probability distribution object by fitting the distribution specified by distname to the data in column vector x.
