Can I use patternsearch to solve a system of non-smooth equations?

I have a system of 42 non-smooth equations with 42 unknowns. To find a numerical solution, I first used fsolve. But the results seem innacurate, probably because of the non-smoothness.

I would like to use patternsearch, from the global optimization toolbox, but the latter needs a scalar objective function if I am not mistaken.

How can I use patternsearch to solve my system of non-smooth equations?

Thanks

Ho, provide your 42 equations in details, so others may try to solve

[Matt Brisson]

Unfortunately, it's quite complicated because the 42 equations are the outcomes of several functions that have to be run by the solver for each new possible solution.

But would it be possible to use patternsearch to solve a system of equations?

Thanks a lot
