Restrict possible values of a symbolic object

Use assumptions to restrict the possible range of values of variables or expressions. For details, see Use Assumptions on Symbolic Variables. To verify if a condition holds, use isAlways.


assume Set assumption on symbolic object
assumeAlso Add assumption on symbolic object
assumptions Show assumptions affecting symbolic variable, expression, or function
clear all Remove items from MATLAB workspace and reset MuPAD engine
in Numeric type of symbolic input
piecewise Conditionally defined expression or function
reset Close MuPAD engine
isAlways Check whether equation or inequality holds for all values of its variables
logical Check validity of equation or inequality


Use Assumptions on Symbolic Variables

Model your problem and get simpler results by using assumptions.

Clear Assumptions and Reset the Symbolic Engine

Remove assumptions and reset the state of the engine.
