LinearDependency
LinearDependency[
op, {op
1
, op
2
, ...}, {x
1
, x
2
, ...}
]
yields a list representing differential operator
op
as a linear compination of operators
op
i
.
MORE INFORMATION
To use
LinearDependency
, you first need to load the
SYM Package
using
Needs
["SYM`"].
The list
{x
1
,x
2
,...}
defines the set of operands the operators
op,
op
i
act upon.
If
op
can be expressed as a linear compination of the operators
op
i
the vector of this linear compination will be returned otherwise, the empty set
{}
.
To define the operators
Partial
can be used.

Basic Examples
(1)
In[1]:=
Let the operator
x
x
+2y
y
. This operator can be expressed with the base
{x
x
, y
y
}
as:
In[2]:=
Out[2]=
Indeed,
In[3]:=
Out[3]=
