change coordinates in a Distribution object
DChange( tr, dist, newvars, options )
dchange( tr, dist, newvars, options )
set of equations corresponding to the transformation from the old variables on the left-hand side of the equations to the new variables on the right-hand side
a Distribution object
list containing the new variables
optional arguments that will be passed down to PDEtools[dchange] command
The DChange method changes coordinates in a Distribution object, and returns a new Distribution object on space with coordinates as specified by the newvars parameter.
The DChange method is closely modeled on the PDEtools:-dchange command, the calling sequence is identical.
The newvars argument is required. Other options are as for PDEtools:-dchange , and are ultimately passed through to it.
The name dchange is provided as an alias.
If the PDEtools package is loaded, a name conflict may arise. In this case the calling sequence should be modified to dist:-DChange(tr, dist, newvars, options).
This method is associated with the Distribution object. For more detail see Overview of the Distribution object.

The Dchange command was introduced in Maple 2020.
