Extruding a 2D plot to 3D

Hello, i want to make the code extrude this curve over the range 0 to 10 units into the z-axis and i want the plot to show it in 3D

i=1;

for k=-5:0.1:5

y(i)=k^2;

x(i)=k;

i=i+1;

end

plot(x,y)

Try this —

k = -5:0.1:5;
y = k.^2;

figure
surf([k;k], [y;y], [ones(size(k))*10; zeros(size(k))])
grid on
colormap(turbo)
shading('interp')
axis('equal')                                                   % Optional
title('Rainbow!')
