1370	EigenValues problem	Martin Sjölund	Martin Sjölund	"{{{[a.mo:10:3-10:75:writable] Error: Wrong type or wrong number of arguments to zeros(size(A, 1), size(A, 1))'.
}}}

The problem is that the function uses a binding with (at the time) unknown dimensions (because the function has yet to be called).
