I'm having a problem generating a gif from a netcdf file.
I am using the script below that I took as a reference in the following link:https://la.mathworks.com/matlabcentral/answers/354954-how-to-make-animation-from-netcdf-file
the google drive link with the netcdf file I used is this: https://drive.google.com/drive/folders/1G8Oj88iqk0g71WLe-p0Q1WN6G5wwGZoq?usp=sharing
the error is in the "surf" command, I don't know how to solve it, does anyone have an idea?
%% script
file = 'data_chirps.2020.12.nc' ;
lon = ncread(file,'longitude') ;
lat = ncread(file,'latitude') ;
t = ncread(file,'time') ;
precip = ncread(file,'precip') ;
% Make animation
filename = 'test.gif';
for i = 1:length(t)
surf(lon,lat,precip(:,:,i))
shading interp
view(2)
drawnow
% Capture the plot as an image
frame = getframe(gcf);
im = frame2im(frame);
[imind,cm] = rgb2ind(im,256);
% Write to the GIF File
if i == 1
imwrite(imind,cm,filename,'gif', 'Loopcount',inf);
else
imwrite(imind,cm,filename,'gif','WriteMode','append');
end
end

Reminder: longitude is y data and latitude is x data but surf requires x then y
