Thanks for the response. Two or three decimal places more should be enough to allow me clearly see the features I am looking at. The problem is that at the moment the inaccuracy is washing them out.
What accuracy are you aiming for?

Greetings,
I am wondering if it is possible to increase the accuracy of sparsediag, for example for the result it gives for the lowest eigenvalue. There does not appear to be a suitable input parameter. My understanding is that increasing accuracy comes at a computational cost, and I need to tweak the balance further to the side of accuracy.
With best regards, Eoin
