How to add pdemesh plot into a matlab gui ?
pdemesh(app.UIAxes1,p,e,t);
doesn't work
mesh(app.UIAxes1,xq,yq,vq1) works

I was able to use this linked post to create a working example. My test app creates the pdemesh shown in this example.

Here is the corresponding ButtonPushed callback function that creates the plot.
% Button pushed function: Button
function ButtonPushed(app, event)
% These 2 lines will ensure that the original HandleVisibility
% values will be restored after this section runs. These lines
% are optional but recommended.
origState = app.UIFigure.HandleVisibility;
handleVisCleanup = onCleanup(@()set(app.UIFigure,'HandleVisibility',origState));
% Temporarily turn on the figure's HandleVisibility so the
% axes are detected by gca()
app.UIFigure.HandleVisibility = 'on';
% Set your app's axes to be current so gca() chooses the correct axes
set(groot, 'CurrentFigure', app.UIFigure)
set(app.UIFigure,'CurrentAxes',app.UIAxes)
% Call the external plotting function
[p,e,t] = initmesh("lshapeg");
pdemesh(p,e,t)
% This line is optional if your function ends here. It will run the
% restoration.
clear handleVisCleanup
end
