The present code is a Matlab function that provides a generation of histogram with superimposed fitted Laplace (double exponential) distribution, similarly to built-in Matlab function “histfit”.

An example is given in order to clarify the usage of the function. For convenience, the input and output arguments are given in the beginning of the function.

The code is based on the theory described in:

[1] N. Johnson, S. Kotz, N. Balakrishnan. Continuous Univariate Distributions Vol. 2. New York, John Wiley & Sons, 1995.

Hi Bess001!

Please, send me your code on my e-mail and will give you a detailed information about the proper implementation of my function. I'd be glad to help!

All best,


Thank you for sharing this program. However, I'm unable to make it run and it displays this error.

Error using xlim (line 31)
Limits must be a 2-element vector of increasing numeric values.

Error in histfitlaplace (line 33)
xlim([mu-1.1*dx mu+1.1*dx]);

Can somebody help me with this issue?
