How to set assumptions in matlab

AI Thread Summary
To set specific assumptions in MATLAB, such as defining that b is less than a, users can utilize the Symbolic Math Toolbox. While basic assumptions like positivity can be set using commands like sym('a','positive'), more complex inequalities require additional steps. Users may need to define symbolic variables and use the 'assume' function for inequalities. For those seeking alternatives, Wolfram Alpha is suggested as a capable tool for handling such mathematical queries. Understanding how to implement these assumptions effectively can enhance integration tasks in MATLAB.
