Does anyone have an ublas implementation of the matlab find() function?
It'll be very useful for vectorizing a wide variety of algorithms. Given
a vector/matrix, the function returns an index array of
the nonzero elements,

template <typename vector_type>
indirect_array<vector_type> ublas_find(const vector_type& data)
