Question

I am using fsurf to plot a surface. I wana make the whole surface a solid color and want to make the surface transparent. How can I do that?

figure
syms x1 x2 
fsurf((B(1)*x1+B(2)*x2+b(1))/-B(3),'EdgeColor','none')

Answer 1

By default FaceColor is set to interp. Change it to your favourite color.

For tranparency use FaceAlpha

figure
syms x1 x2 
fsurf((B(1)*x1+B(2)*x2+b(1))/-B(3),'EdgeColor','none',...
    'FaceColor','r','FaceAlpha',0.5);
