How to indicate the number of nodes and elements of mesh of PDE problem in command line? (the function pdeplot can't do this)

Now, I have set up a PDE model mesh in command line rather than GUI in PDE App. I want to indicate the number of nodes and elements of my mesh, I have try to use the function pdeplot and pdegplot but fail to indication! I know I can indicate the number of nodes and elements in PDE App if you generate your mesh in GUI manner in your App. but I would like to set completely up my PDE model in command line (using Code). So how can I get the indication of number of nodes and elemnts?

Try using:

pdemesh(modelM,'NodeLabels','on')

Does it not show labels of node for you?

Thanks for your answer. But your code does not show labels of node of my mesh (2D), and the function pdemesh does not include the the input parameter of NodeLabels in Matlab help doc. My Matlab is the version of R2015b .pdemesh(modelM,'NodeLabels','on') can show labels of node in your Matlab?

I will appreciate you very much if you can give me some more detailed explaination!

You need newer version of MATLAB to plot note labels. Please upgrade to R2016b or newer.
