MATLAB is a numerical computing environment and programming language. Maintained by The MathWorks, MATLAB allows easy matrix manipulation, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs in other languages. Although it is numeric only, an optional toolbox uses the MuPAD symbolic engine, allowing access to computer algebra capabilities. An additional package, Simulink, adds graphical multidomain simulation and Model-Based Design for dynamic and embedded systems.
There is an alternative to MATLAB, but only for specific tasks. MATLAB is a more global application package that helps to solve almost all tasks related to mathematical modeling and for engineering assignments in general. In addition, MATLAB is an eponymous language, which is a high-level interpreted programming language and makes it possible to write programs of two types - functions and scripts. I also use resource https://assignment.essayshark.com/matlab-help.html to ask experts about specific assignments and just to check them. There is also the [Mathcad](https://alternativeto.net/software/mathcad/) program - it's a computer algebra system that you can use to visualize your math calculations.
