It can be an invaluable tool, helping to save hours of frustrating pencil time and avoiding careless mistakes. (See Programming and Data Types in the online MATLAB documentation for an introduction to MATLAB classes and objects.) Internally, a symbolic object is a data structure that stores a string representation of the symbol. Matlab as a tool, not a crutch Matlab’s Symbolic Math Toolbox (or any other symbolic algebra program) can be used to find analytical solutions to problems. Perform polynomial multiplication and simplify the results, show that ( x - 1 ) ( x + 1 ) ( x 2 + x + 1 ) ( x 2 + 1 ) ( x 2 - x + 1 ) ( x 4 - x 2 + 1 ) simplifies to x 1 2 - 1. Symbolic Objects The Symbolic Math Toolbox defines a new MATLAB data type called a symbolic object. Most mathematical expressions can be represented in different, but mathematically equivalent forms and the Symbolic Math Toolbox supports a number of operations, including factoring or expanding expressions, combining terms, rewriting or rearranging expressions, and simplification based on assumptions. You can create, run, and share symbolic math code using the MATLAB® Live Editor. The Symbolic Math Toolbox supports the Formula Manipulation and Simplification of mathematical functions. Symbolic Math Toolbox provides functions for solving, plotting, and manipulating symbolic math equations.
