예제 및 방법

Enforce Evaluation

MuPAD automatically evaluates results returned by most of the system functions.

Prevent Evaluation

When you perform interactive computations in MuPAD, the system tries to evaluate all expressions before returning them.

Evaluate at a Point

To evaluate an expression for particular values of identifiers, use the evalAt function or its shortcut |.

개념

Evaluations in Symbolic Computations

Evaluation is one of the most common mathematical operations.

Level of Evaluation

The value of an identifier can contain arbitrary MuPAD objects, including identifiers.

Actual and Displayed Results of Evaluations

When MuPAD evaluates an expression or executes a command, the output that the system displays can differ from the actual result.
