Research direction

Start by checking whether Julia already provides the Matlab sprank equivalent and locating the matrix equilibration or normalization code in MatrixNetworks.jl. Read the graph theory characterization described in the issue, then determine the project entry point and tests needed for a structural-rank function. Done means the requested capability is available in Julia with behavior covered by tests.

Written by the indexing model from the issue text.

Description

One of the issues in matrix equilibration/normalization/etc is the structural rank of a matrix. This asks if there is an assignment of values to the non-zero elements such that the matrix is full-rank. There is a nice graph theory characterization we should add if julia doesn't have it. (this is the sprank function in Matlab)
