DifferentialRootReduce
DifferentialRootReduce[expr,x]
attempts to reduce expr to a single DifferentialRoot object as a function of x.
DifferentialRootReduce[expr,{x,x0}]
takes the initial conditions to be specified at x=x0.
Details and Options
- DifferentialRootReduce will attempt to represent any expression as a DifferentialRoot object.
- DifferentialRootReduce[expr,x] always gives exactly 0 when the DifferentialRoot object for expr is equivalent to the zero function.
- DifferentialRootReduce automatically threads over lists, as well as equations and inequalities.
- DifferentialRootReduce[f] operates on a pure function or pure DifferentialRoot object.
