Hello, I am working on a simulation which diagonalizes a matrix for me, then I take the eigen vectors of said matrix and build a density of states. For computational purposes this is just an NxN matrix and each elements magnitude is the density of states at a specific location.
I am wondering if anyone has a good way to plot these values such that there is an interpolation between neighboring values and decent resolution. I am currently using pcolor and setting this to interpolate, but this does not seem to have the resolution I am after. Maybe there is a way to increase resolution and I am not aware of it?
Any ideas will be appreciated!

Hi,
With my understanding of the question, I believe interpolating the N*N matrix before passing to the pcolor will help in increasing the resolution.
For interpolating the N*N matrix you can use the imresize function.
I would also recommend to look at the following density plotting function,
Hope this helps!

What package do you need for densityplot actually? Matlab says unknown variable when I try...
