Is there a direct way to use SLEPC from Matlab? I remember that in some old manuals there was some Matlab interface. However, in the last one, I cannot find any reference to this. For me it would be really useful in the computation of eigenvalues for some large, sparse matrices.
(Matlab's eigs does a pretty good job for matrices up to $12e6\times 12e6$ (that I tested), but with huge cost in RAM. I'm not sure if parallelization will consume as much or more...)
Are there any tutorials, packages which can make the connection between the two: Matlab and Slepc?
