This Matlab binary contains matrices and .
I regard the following as a very difficult problem, having spent considerable time with it.
Matrix is sparse having only 1,170,516 nonzeros.
All entries of are integers from the set .
.
Vector is left unspecified because it is varied later as part of a Convex Iteration.
Vector may arbitrarily be set to or .
