May I ask what MATLAB code for expected value is by fitting a Poisson distribution?

A = [1, 2, 3, 4, ..., 100]
In this case, I want to fit a Possion distribution and get the expected value.
Would you please tell me how to do it?

Ran in:
A = 1:100;
lambdahat = poissfit(A)
lambdahat = 50.5000

That would be a terrible fit. An upwardly increasing ramp in no possible way has any shape remotely like a Poisson distribution and you should not fit one to that data. It will not be a reliable model at all. That fit cannot be used in place of your actual data to predict or estimate anything.

The data do not remotely look random. More like a trial balloon. So who cares ?
