How to get data from a plot out as data in Matlab?

Please login with a confirmed email address before reporting spam

Dear group.

I use Comsol 35a and have a Matlab script which solves for acoustic pressure in 2D at some distance from a boundary. I then plot the pressure in the y-direction [0 0;0 1] with:

postcrossplot(fem,1,[0 0;0 1], ...
'lindata','p', ...
'npoints',10000, ...
'title',['Pressure [Pa]'], ...
'axislabel',{'Arc-length','Pressure [Pa]'});

This works fine (I modified the code generated by saving my model as a m-file).

But I would also like the values out as s string of data in Matlab for postprocessing. I cannot get 'posteval' or 'postinterp' to work properly, due to limited experience. It sounds like a simple problem, but I am kind of stuck and hope somebody jsut knows how to to do this ......

Best regards

Kasper
