spar_gen_bandish(nrows, ncols, seed)

spar_gen_banded(nrows, ncols, band = 2)

`nrows, ncols`	The dimension
`seed`	Random seed.
`band`	The band size, a positive integer. `band=1` returns a matrix whose diagonal entries are all 1; `band=2` returns a matrix with 1 on each diagonal entry and 1 on each entry directly above and below the main diagonal; etc.

spar_gen_bandish() generates a "band-ish" matrix, a matrix whose entries are probabilistically more likely to be 1 the closer to the main diagonal they are.

spar_gen_banded() generates a banded matrix.

A sparse "dgCMatrix" object is returned.
