Calling Sequence

InitialData( obj, opts)

Initialdata( obj, opts)

Parameters

obj

-

a LHPDE object

opts

-

(optional) sequence of options to control the behaviour of DEtools[initialdata]

Description

• 

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.
