MATLAB-Probability-Distributions-Visualizer

An interactive MATLAB App Designer tool for real-time visualization of continuous and discrete probability distributions, PDFs, and CDFs.

📊 Interactive Probability & Statistics Explorer

An interactive MATLAB application designed to visualize continuous and discrete probability distributions in real time as the parameters change with synchronized PDF/PMF and CDF plots. Credits: The descriptions of the distributions are form the "Seeing Theory" website: https://seeing-theory.brown.edu/probability-distributions/index.html#section2

✨ Features

• Continuous & Discrete Distributions: Visualizes Normal, Uniform, Student's T, Chi Squared, Exponential, F, Gamma, Beta, Bernoulli, Binomial, Geometric, Poisson and Negative Binomial distributions.
• Real-time Parameter Sliders: Interactively change mean, standard deviation, number of trials, or probability values to see plots update instantly.
• CDF/CMF Tracking: Toggle and overlay Cumulative Distribution Functions dynamically on top of density plots.
• Interactive UI: Smooth transitions, auto-scaling axis bounds, and clean layout built with MATLAB App Designer.
