What does the example do?

[gdalle]

The file https://github.com/michel2323/ColPack.jl/blob/master/examples/coloring.jl doesn't seem to be used anywhere, and it tries to read a matrix from a file without downloading it first

[michel2323]

That's indeed messy. ColPack has an mtx reader.

[gdalle]

I removed it in #11

[amontoison]

We should keep it in a section of the documentation.
It is always useful to have a script to try the algorithm directly on mtx files.

[gdalle]

Okay but this script doesn't run anyway since the downloading part is not written. Feel free to add something that uses e.g. https://github.com/JuliaLinearAlgebra/MatrixDepot.jl

[amontoison]

Ok I was not aware of that.
It's a good idea to remove the file in that case.

[gdalle]

I want to add more docs anyway once I figure out how the package works (e.g. with #12). I can always add an example where a matrix is downloaded from the sparse matrix connection, stored in mtx and then retrieved. But I want it to actually run in the docs, not just be some displayed code

[amontoison]

The package SuiteSparseMatrixCollection.jl can download and install the mtx files for you as an artifact.
