How to randomly sample points within some range using a distribution fit obtained from distribution fitter app?

I am used distribution fitter app to fit a probability distribution on my data, and I am able to save distribution object to workspace.

Now I want to use newly fitted distribution to generate random numbers within a desired range. 

Please help me in achieving this workflow.

As a workaround, please try the following steps:

• Save the probability distribution object from the "distributionFitter" app to the workspace. It usually saves a variable named "pd".
• Use the "truncate" function to create a new distribution object within the desired limits.
• Use the "random" function to generate numbers randomly using the distribution object.

>> pd_truncated = truncate(pd,45,60); >> number = random(pd_truncated)

For more details, you can refer to the documentation about the "truncate" function by executing the commands in the MATLAB R2020a command window:

>> web(fullfile(docroot, 'stats/prob.normaldistribution.truncate.html'))

For more details, you can refer to the documentation about the "random" function by executing the commands in the MATLAB R2020a command window: 

>> web(fullfile(docroot, 'stats/prob.normaldistribution.random.html'))
