Hello,

I am solving an eigenvalue problem so a bunch of functions are being generated. What is the best way to do this? Can I just save each plot to a separate file using cout or should I save the function values into different files and plot them with matlab.

Thank you for the help.

Just use ParaView, [here](https://github.com/FreeFem/FreeFem-sources/blob/master/examples/hpddm/laplace-adapt-3d-PETSc.edp#L40) is an example where multiple plot are output and then you can just open a single file.
