I am trying to plot the 3D surface given by the zero of a function. I have a complicated function given by

```
function mcl(Y,w)
BLAH BLAH
end
```

Where Y is a 2-element Array{Int64,1} and w is a real number. For example

```
mcl([1,1],1)
-0.5630978416902811
```

I would like to plot the 3D-surface given by mcl(Y,w) = 0.

I searched in several threads but didn’t find any similar resolution.
