Simplify symbolic expressions in Live Editor
The Simplify Symbolic Expression task enables you to interactively simplify or rearrange symbolic expressions. The task automatically generates MATLAB® code for your live script. For more information about Live Editor tasks, see Add Interactive Tasks to a Live Script.
Using this task, you can:
Perform algebraic simplification of symbolic expressions.
Rewrite expressions in terms of another function.
Expand algebraic expressions.
Combine terms of identical algebraic structure.
Generate the code used to simplify or rearrange expressions.
To add the Simplify Symbolic Expression task to a live script in the MATLAB Editor:
On the Live Editor tab, select Task > Simplify Symbolic Expression.
In a code block in your script, type a relevant keyword, such as
Symbolic Expression from the suggested command completions.
Method— Specify simplification method
Specify the simplification method from the drop-down list:
|Perform algebraic simplification.|
|Simplify symbolic rational expressions.|
|Rewrite expressions in terms of another function.|
|Expand expressions and simplify inputs of functions by using identities.|
|Combine terms of identical algebraic structure.|
Effort— Specify computational effort used to simplify
Specify the computational effort used for the
from the drop-down list:
|Minimum||Minimum effort with fastest computation time (can return most complicated result)|
|Low||Low effort with faster computation time|
|Medium||Medium effort with normal computation time|
|High||High effort with slower computation time|
|Full||Full effort with slowest computation time (can return simplest result)|
Multiply out brackets— Multiply out brackets when expanding expressions
Select this check box to not expand special functions for the
Expand method. This option expands the arithmetic part of an
expression, such as powers and roots, without expanding trigonometric, hyperbolic,
logarithmic, and special functions.
Ignore analytic constraints— Ignore analytic constraints when expanding expressions
Select this check box to apply purely algebraic simplifications to give simpler
solutions for the
Expand method, which could lead to results not
generally valid. This option applies mathematical identities that are convenient, but do
not always hold for all values of variables. In some cases, this option can lead to
simpler results that are not equivalent to the initial expression.
