ce07e37 is described below
commit ce07e37231cecc2979e5e28c714fc1e19b612ef2
Author: baunsgaard <baunsga...@tugraz.at>

[MINOR] Improve sparse matrix printing
This commit change the sparse printing to only print rows, that actually
contain values. Also included is a small test of unary operations on
dense, CSR, and MCSR.
Closes #1458
