Examples and How To

Use Permanent Assumptions

Permanent assumptions work best for the mathematical properties that hold true throughout your computations.

Use Temporary Assumptions

Use temporary assumptions to specify that an object holds mathematical properties for a particular calculation.



Use only in the MuPAD Notebook Interface.

When to Use Assumptions

By default, MuPAD® assumes that all symbolic parameters and variables represent complex numbers.
