**MATLAB and R** have different libraries and code syntax, but the same functionalities.

The Neural Network Toolbox, the Optimization Toolbox, Statistics Toolbox, and Curve Fitting Toolbox are each highly desirable for someone using **MATLAB** for ML/Data Mining work, but they are all separate from the base MATLAB environment--in other words, they have to be purchased separately.

**MATLAB** is commercial and commonly used for mathematical processing. MATLAB is pretty slower than R and Python.

**R **is used for **statistical analysis** and** data processing** on a small scale. It has a very vast collection of packages, that are used to do almost anything you might imagine with data and they are easy to install. As a general programming language, it is much slower than Python and the syntax is quite confusing.
