The GetDependents method returns a list of dependent variables for a LHPDE object.

The default output is a list of functions. The dependent variables can also be returned as a list of names, by specifying 'output'= "names".

This method is associated with the LHPDE object. For more detail, see Overview of the LHPDE object.

$\mathrm{with}\left(\mathrm{LieAlgebrasOfVectorFields}\right)\:$

$S≔\mathrm{LHPDE}\left(\left[\mathrm{diff}\left(u\left(x\,y\right)\,x\,x\right)-\mathrm{diff}\left(v\left(x\,y\right)\,y\,y\right)=0\right]\right)$

$S≔\left[\frac{{\partial }^2}{\partial x^2}u\left(x\,y\right)-\frac{{\partial }^2}{\partial y^2}v\left(x\,y\right)=0\right],\mathrm{indep}=\left[x\,y\right],\mathrm{dep}=\left[u\left(x\,y\right)\,v\left(x\,y\right)\right]$

$\mathrm{GetDependents}\left(S\right)$

$\left[u\left(x\,y\right)\,v\left(x\,y\right)\right]$

$\mathrm{GetDependents}\left(S\,'\mathrm{output}'=''names''\right)$

$\left[u\,v\right]$

The GetDependents command was introduced in Maple 2020.
