I was working on adding the MATLAB isosurface functionality to matlab_plotly. Issue #386 reports that matlab_plotly does not have support for the isosurface functionality. So I started adding it. Since matlab_plotly did not have support for this functionality, to solve this I had to code everything necessary from scratch. Specifically, I have coded a whole file for this which I have called updateIsosurface.m.
Now, to use this functionality, when invoking fig2plotly it is necessary to set the optional parameter 'TreatAs' to 'isosurface'

Example 1

[x,y,z] = meshgrid([-3:0.25:3]); 
V = x.*exp(-x.^2 -y.^2 -z.^2);
isosurface(x,y,z,V,1e-4);

Example 2

[x,y,z] = meshgrid([-3:0.25:3]); 
V = x.*exp(-x.^2 -y.^2 -z.^2);
s = isosurface(x,y,z,V,1e-4);
p = patch(s);
isonormals(x,y,z,V,p)
view(3);
set(p,'FaceColor',[0.5 1 0.5]);  
set(p,'EdgeColor','none');
camlight;
lighting gouraud;

Example 3

[x,y,z] = meshgrid([-3:0.25:3]); 
V = x.*exp(-x.^2 -y.^2 -z.^2);
[faces,verts,colors] = isosurface(x,y,z,V,1e-4,x);
patch('Vertices',verts,'Faces',faces,'FaceVertexCData',colors,...
    'FaceColor','interp','EdgeColor','interp')
view(3) 
colormap copper

Example 4

[x,y,z,v] = flow;
p = patch(isosurface(x,y,z,v,-3));
isonormals(x,y,z,v,p)
p.FaceColor = 'red';
p.EdgeColor = 'none';
daspect([1 1 1])
view(3);
