Description

Compatibility
IsSubspace( obj1, obj2)
obj1
-
a LHPDE object that is assumed to be in rif-reduced form (see IsRifReduced)
obj2
a LHPDE object
The IsSubspace method returns true if solution space of obj1 is a subspace of solution space of obj2. False otherwise.
More precisely, the method returns true if at each point [Math Processing Error], the local solution space of obj1 at [Math Processing Error] is a subspace of the local solution space of obj2 at [Math Processing Error].
The input arguments obj1 and obj2 need not have the same dependent variable names or dependencies.
This method is associated with the LHPDE object. For more detail, see Overview of the LHPDE object.
[Math Processing Error]
This LHPDE object's dependent variables have different names and dependencies.
The IsSubspace command was introduced in Maple 2020.
For more information on Maple 2020 changes, see Updates in Maple 2020.
