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

distributionfitterMATLABpdfpointsrandomsampletruncate

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.

Best Answer

As a workaround, please try following steps:

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

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

You can use the "yyaxis" and "ylim" commands to set the y-limit for both axes:

>> figure

>> yyaxis left

>> plot(1:10);

>> yyaxis right

>> plot(2:2:20);

>> f = gcf;

>> yyaxis left

>> ylim(f.Children, [0 5]);

>> yyaxis right

>> ylim(f.Children, [5 10]);

You can use "imread" and "image" in a a for-loop to create a pictogram.

>> x = [1 2 3 4];
>> y = [2 4 3 2];
>> im = imread('peppers.png');
>> figure
>> hold on
>> xPos = [1 0.1];
>> yPos = [1 0.1];
>> for i = 1:numel(x)
>>     xPos = xPos + 1;
>>     for j = 1:y(i)
>>         image(xPos, yPos, im)
>>         yPos = yPos + 1;
>>     end
>>     yPos = [1 0.1];
>> end
