Using MATLAB we can incredibly plot 3-D surfaces just by entering a _mathematical expression_ given by  
`z = f(x, y)`. We can do this using the MATLAB function `fsurf`.

Now, depending on the mathematical expression that we pass as the input argument in `fsurf`, MATLAB will show us really interesting 3-D surfaces. But, `fig2plotly` will go further 😃 🕶

To address the `fsurf` functionality, you just need to invoke `fig2plotly` at the end of your MATLAB code and set the optional `'offline'` parameter to `true` or `false`, depending on the **offline/online mode** you want to use. Let’s see the following example

```auto
r = @(u,v) 2 + sin(7.*u + 5.*v);
funx = @(u,v) r(u,v).*cos(u).*sin(v);
funy = @(u,v) r(u,v).*sin(u).*sin(v);
funz = @(u,v) r(u,v).*cos(v);
fsurf(funx,funy,funz,[0 2*pi 0 pi]) 
camlight;

fig2plotly(gcf, 'offline', false); % online mode

```

After executing the above code, the charts generated by MATLAB and `fig2plotly` are shown in the following image.

As we can see, on the left of the screenshot above appears the surface plotted by MATLAB, but on the right we delight in the beauty of Plotly.

Following this [link](https://chart-studio.plotly.com/~galvisgilberto/4370/#/), you will be able to experience this directly in Chart-Studio.

[Here](https://github.com/plotly/ssim_baselines/tree/main/matlab/code-examples/surface-and-mesh-plots/fsurf) you can find more examples using `fsurf`, which you can recreate using `fig2plotly` . Please try to do it! I did it and was fascinated again! 😆 I attach below screenshots with results from my end
