How do I export p, t, u, and c back to the workspace using the command line in the PDE Toolbox?

I am using the PDE Toolbox and would like to use the PDESMESH function. I would like to export mesh and edge variables from the workspace to the command line. I would like to know if there is a way to export the parameters of PDE Tool back to the workspace using the command line instead of the GUI.

Here is a function that will export the parameters p, t, u, c, a, f, d, b, and g back to the workspace using the command line instead of the GUI:

For MATLAB 8.0 (R2012b) and earlier releases you can use the following two commands to extract the data to MATLAB Workspace when PDETOOL is active.

pde_fig=findobj(allchild(0),'flat','Tag','PDETool')

u = get(findobj(pde_fig,'Tag','PDEPlotMenu'),'UserData');

MATLAB 5.x and above compatible:

============================

function [p,e,t,u,l,c,a,f,d,b,g] = getpetuc

%GETPETUC Get p,e,t,u, and c.

pde_fig=findobj(allchild(0),'flat','Tag','PDETool');

if isempty(pde_fig)

    error('PDE Toolbox GUI not active.')

end

u = get(findobj(pde_fig,'Tag','PDEPlotMenu'),'UserData');

l =get(findobj(pde_fig,'Tag','winmenu'),'UserData');

h=findobj(get(pde_fig,'Children'),'flat','Tag','PDEMeshMenu');

hp=findobj(get(h,'Children'),'flat','Tag','PDEInitMesh');

he=findobj(get(h,'Children'),'flat','Tag','PDERefine');

ht=findobj(get(h,'Children'),'flat','Tag','PDEMeshParam');

p=get(hp,'UserData'); 

e=get(he,'UserData');

t=get(ht,'UserData');

params=get(findobj(get(pde_fig,'Children'),'flat','Tag','PDEPDEMenu'),...

        'UserData');

ns=getuprop(pde_fig,'ncafd');

nc=ns(1); na=ns(2); nf=ns(3); nd=ns(4);

idxstart = 1;

idxstop = nc;

c=params(idxstart:idxstop,:);

idxstart = idxstart+nc;

idxstop = idxstop + na;

a=params(idxstart:idxstop,:);

idxstart = idxstart+nc;

idxstop = idxstop + nf;

f=params(idxstart:idxstop, :);

idxstart = idxstart+nf;

idxstop = idxstop + nd;

d=params(idxstart:idxstop,:);

hbound = findobj(get(pde_fig,'Children'),'flat','Tag','PDEBoundMenu');

g = get(hbound, 'userdata');

hb_cld = get(hbound, 'children');

b = get(hb_cld(7), 'userdata');

MATLAB 4.2c compatible: (This version only exports p, e, t, u and c)

=====================

function [p,e,t,u,c] = getpetuc

%GETPETUC Get p,e,t,u, and c.

pde_fig = findobj(get(0,'Children'),'flat','Tag','PDETool');

if isempty(pde_fig)

    error('PDE Toolbox GUI not active.')

end

u = get(findobj(pde_fig,'Tag','PDEPlotMenu'),'UserData');

h=findobj(get(pde_fig,'Children'),'flat','Tag','PDEMeshMenu');

hp=findobj(get(h,'Children'),'flat','Tag','PDEInitMesh');

he=findobj(get(h,'Children'),'flat','Tag','PDERefine');

ht=findobj(get(h,'Children'),'flat','Tag','PDEMeshParam');

p=get(hp,'UserData'); 

e=get(he,'UserData');

t=get(ht,'UserData');

params=get(findobj(get(pde_fig,'Children'),'flat','Tag','PDEPDEMenu'),...

        'UserData');

ns=getuprop(pde_fig,'ncafd');

nc=ns(1); na=ns(2); nf=ns(3); nd=ns(4);

c=params(1:nc,:);
