The Symbolic Math Toolbox includes functions for solving, visualizing, and manipulating symbolic math equations. In combination with MATLAB’s Live Editor, it provides an easy, intuitive, and complete environment to interactively learn and teach algebra, calculus, and ordinary differential equations.

Starting with MATLAB R2021a, you can represent matrices and vectors in compact matrix notation with a new symbolic matrix variable data type. This enables a concise typeset display and show mathematical formulas with more clarity. Using them, you can show matrix- and vector-based expressions the way they are displayed in textbooks.

Contrast the visual difference between matrices of symbolic scalar variables and the new symbolic matrix variables:

The syms and symmatrix functions create symbolic matrix variables. To convert a symbolic matrix variable to an array of symbolic scalar variables, use symmatrix2sym. For an example, see Create Symbolic Matrix Variables.
