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)
