Analyze and model data using statistics and Machine Learning.

Statistics and Machine Learning Toolbox provides functions and apps to describe, analyze, and model data. You can use descriptive statistics, visualizations, and clustering for exploratory data analysis, fit probability distributions to data, generate random numbers for Monte Carlo simulations, and perform hypothesis tests. Regression and classification algorithms let you draw inferences from data and build predictive models either interactively, using the Classification and Regression Learner apps, or programmatically, using AutoML.

For multidimensional data analysis and feature extraction, the toolbox provides principal component analysis (PCA), regularization, dimensionality reduction, and feature selection methods that let you identify variables with the best predictive power.

The toolbox provides supervised, semi-supervised and unsupervised machine learning algorithms, including support vector machines (SVMs), boosted decision trees, k-means, and other clustering methods. You can apply interpretability techniques such as partial dependence plots and LIME, and automatically generate C/C++ code for embedded deployment. Many toolbox algorithms can be used on data sets that are too big to be stored in memory.

MATLAB Coder generates readable and portable C and C++ code from Statistics and Machine Learning Toolbox functions that support code generation. You can integrate the generated code into your projects as source code, static libraries, or dynamic libraries. You can also use the generated code within the MATLAB environment to accelerate computationally intensive portions of your MATLAB code. Generating C/C++ code requires MATLAB Coder and has the following limitations:

- You cannot call any function at the top level when generating code by using codegen. Instead, call the function within an entry-point function, and then generate code from the entry-point function. The entry-point function, also known as the top-level or primary function, is a function you define for code generation. All functions within the entry-point function must support code generation.
- The MATLAB Coder limitations also apply to Statistics and Machine Learning Toolbox for code generation. For details, see “MATLAB Language Features Supported for C/C++ Code Generation” (MATLAB Coder).
- Code generation in Statistics and Machine Learning Toolbox does not support sparse matrices.
- For the code generation usage notes and limitations for each function, see the Code Generation section on the function reference page.
