Description

It would be great to be able to read and write to MatrixMarket formats. Is anyone working on this? If not, I could make an implementation if time allows.

Contributor guide

Research direction
Study the existing IO classes in Breeze for reading and writing matrices. Understand the Matrix Market format (coordinate and array formats). Write functions to parse and serialize. Add tests.
