Applications
Symbolic Math Toolbox provides tools to solve, plot, and manipulate mathematical expressions, both analytically and numerically with high precision. From the results of symbolic computations, you can also generate MATLAB® functions, Simulink® Function blocks, and Simscape™ equations to use with other toolboxes. Use these tools to perform application-specific workflows.
