`maximum` works on my fairly recent Julia build. So you can upgrade Julia or just use the function which is now included with Julia:
```
function maximum{T}(A::SparseMatrixCSC{T})
isempty(A) && throw(ArgumentError("argument must not be empty"))
m = maximum(A.nzval)
nfilled(A)!=length(A) ? max(m,zero(T)) : m
end
```
