Hello I need help.
We have a random variable and we start by getting the histogram of this random variable.
Can someone give me a code to extract from the histogram the distribution of this random variable?

Do you have the underlying data, or only the counts from each bin?
Were you hoping to find a particular functional form (e.g. a normal distribution), or is something purely empirical OK?
Depending on the answers to these questions, the ksdensity function might be useful (if you have the Statistics and Machine Learning Toolbox).

Hello Thank you for your answer.
This is my histogram and what I need is to estimate the distribution of probability.
I think ksdensity is what I am searching for.
Thank you
