is an option for Simplify and FullSimplify which gives the list of functions to apply to try to transform parts of an expression.
TransformationFunctions
is an option for Simplify and FullSimplify which gives the list of functions to apply to try to transform parts of an expression.
Details
- The default setting TransformationFunctions->Automatic uses a built‐in collection of transformation functions.
- TransformationFunctions->{f1,f2,…} uses only the functions fi.
- TransformationFunctions->{Automatic ,f1,f2,…} uses built‐in transformation functions together with the functions fi.
Examples
Basic Examples (2)
Specify that Simplify should use t as the only transformation:
Here Simplify uses both t and all built-in transformations:
By default FullSimplify does not use Reduce :
Specify that FullSimplify should use Reduce with respect to x over the real domain:
