Plotting surface instead of line

I am creating a gif of a number of 3D plots where x and y are between 0 and 1. However, MatLab is only plotting the data (which is stored in a matrix) of the line where x and y are equal, and not the total surface.
How can I fix it? Thank you in advance
Here is the figure code:
n = 1:steps;
nImages = length(n);
x = (0:0.05:1)';
y = (0:0.05:1)';
fig = figure;
for idx = 1:nImages
z = final_matrix(:, :, idx);
plot3(x,y,z,'LineWidth',3)
xlim([0 1]);
ylim([0 1]);
zlim([0 5]);
xlabel('\xi');
ylabel('\eta');
title(['\phi for \tau = ' num2str( n(round(idx, 3))*0.025 - 0.025) ])
drawnow
frame = getframe(fig);
im{idx} = frame2im(frame);
end
close;
