It's a sparse array so that is standard.

You can use:

full( kio )

to convert to a full (standard) matrix if you wish, though be aware that it will take more memory. Obviously for a 78x78 matrix this is not an issue though.

Adam is completely correct of course. I would only add the additional point that a sparse 78x78 matrix is REALLY small these days. Any computations will not be that much faster for such a small matrix. Sparse matrix computations might even be slower. It is worth testing for your matrix.
