One other detail: I set the first column-variable >=1.0 to exclude the zero-vector as a solution, which would otherwise satisfy all the constraints as well as minimize the objective-function. The example below satisfies the >=1.0 constraint as well: > An example of a feasible-point is the following, in order of the columns > they mutliply with: > > 201.34 > 96.09 > 0.796 > 0.842 > 1 > 0.05 > 89.84 > 0.07 > 53.78 > 0 > 0 > I can probably come up with additional constraints on the variables. I would expect additional constraints to affect the time it takes to converge to a solution, though, and not make the system feasible if it wasn't before.
