Sparse manual deff.

I find:

The band density is defined as the number of non-zero values in the matrix divided by the number of non-zero values in the matrix. 

This will always be 1  ??????

Also Does Octave use:

"

Yale format

The Yale Sparse Matrix Format stores an initial sparse m×n matrix, M, in row form using three one-dimensional arrays.

"

to work with sparse matrix   ????
