Here are a ton of them:
Is the one you want in that list? If not, you'll have to use inverse transform sampling, like my attached example, and described here in Wikipedia.

and in particular https://www.mathworks.com/help/stats/makedist.html and https://www.mathworks.com/help/stats/random.html
If you want to sample unequally from a specific list of values, then use randsample() and use the W (weight) parameter.

See https://www.mathworks.com/help/stats/nonparametric-and-empirical-probability-distributions.html for functions to create empirical distributions from data.
"User-defined custom distributions, created using files and function handles, are supported by the Statistics and Machine Learning Toolbox™ functions pdf, cdf, icdf, and mle, and the Statistics and Machine Learning Toolbox Distribution Fitter app."
