InitialData( obj, opts)
Initialdata( obj, opts)
obj
-
a LHPDE object
opts
(optional) sequence of options to control the behaviour of DEtools[initialdata]
The InitialData method is a front-end to the existing command DEtools[initialdata], which accepts a LHPDE object as the first input argument.
All optional arguments will be passed down to DEtools[initialdata].
Let S be a LHPDE object then InititalData(S, opts) is equivalent to DEtools[initialdata](GetSystem(S), GetDependents(S), opts).
The method name Initialdata is provided as an alias.
This method is associated with the LHPDE object. For more detail, see Overview of the LHPDE object.

The InitialData command was introduced in Maple 2020.
