Fix compilation error caused by wrong array initialization

We usually don't silence migh-be-uninitialized warning (which is the only
thing which could explain setting matrix to all zeroes) so we can catch
such errors when using tools like Valgrind.

I don't get warning here and the initializer was wrong, so removing it.

If it-s _REALLY_ needed please do a proper initialization.
