How do I smooth a curve on a surf plot?

I have been trying to "smooth" out this curve in MATLAB but have been unable to. The goal is to have a smoother curve depicted in this surf plot. Any ideas?
I have attached the code needed to make the figure to and I used the code below to generate this figure
surf(ZFF_vals, DFF_vals, Fin

I think even with the shading, the data still looks rough. I was looking for something that more of alters the data, that way the curve isnt as rough. I am trying to alter this data so that it becomes a smooth curve.

You can try smoothdata() with Gaussian, e.g.:
X = load('DFF_vals.mat');
Y = load('ZFF_vals.mat');
Z = load('Fin.mat');
Zsmooth = smoothdata(Z, 'gaussian', 25);
subplot(211)
mesh(X,Y,Z)
subplot(212)
mesh(X,Y, Zsmooth), view([30, 45, 30])

Thanks for responding. I was looking for something that more of alters the data, that way the curve isnt as rough. Something that maybe gets rid of the outliers and introduces new data points where the curve is if that makes sense.
