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?

在 MATLAB Online 中打开

Try using:

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

Does it not show labels of node for you?

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