 # Workflow
 To call a Julia function using MATFrost, the Julia function needs to satisfy some conditions. These conditions include fully typed input signatures and single method implementation (see later section for more info on these conditions). These conditions have been set to remove interface ambiguities but goes against the overall Julia vision of aiming for high extensibility. What this means in practice is that to be able to call Julia functions from MATLAB, very likely, a MATFrost Julia interface function needs to be created that wraps around Julia functionality.
