Is there a collection of matrices like Matlab's gallery?

Hi everyone,

Since Julia is very suitable for experimenting with new numerical methods, I was wondering if there is a collection of “famous” matrices somewhere. I am thinking of something like Matlab’s gallery of matrices, but it does not have to be as rich.

I have already seen some packages write their own “special matrices” for testing purposes, so I see a use case for having a repository of those matrices somewhere. For example, symmetric sparse matrices, ill-conditioned matrices, …etc. If there isn’t a such collection out there, then let me know if you think it is something you’d like to have or if you have specific matrices in mind that you’d like to see there.

Take a look at MatrixDepot.jl

That is exactly what I am looking for. Thank you for sharing.
