Here is one way to do this with Cupid
% Create a custom mixture distribution:
% Use whatever distribution parameters and mixture probability you want.
mybeta = Beta(5.3,4.1);
mygamma = RNGamma(17,10);
mycustom = Mixture(.3,mybeta,.7,mygamma); % .3 is the probability of mybeta
mycustom.PlotDens; % Plot the PDF and CDF of the custom distribution
myrands = mycustom.Random(100,1); % generate 100 random numbers.

There must be some problem with the download/installation from GitHub. Do you see the file Mixture.m in the same folder with Beta.m and RNGamma.m (and all the other files)? You should. Also, MATLAB must see these files, you must either point MATLAB to this folder or put this folder on the MATLAB path.
