Hi

in V3.5 with matlab you can do something like:

flist = []
for k = 1:length(fem.sol.lambda)
flist = [ flist ; -imag(fem.sol.lambda(k))/2/pi ]
end

and you have your list in "flist"

Else you can do a copy paste ibelieve from the list in te GUI (not sure)

you have alos this one to plot a series

function plot_eigenfrequency(fem,N)

for i=1:N

postplot(fem,...
'tridata','your_solution',...
'solnum',i);

end


Good luck
Ivar

Hello Ivar!

I managed it in V4.0 with Results -> Derived Values -> Point Evaluation -> Copy Table to Clipboard.
Thanks for your help!
