How to calculate average of Netcdf daily data

I am able to read the netcdf file format. But how to calculate average? Suppose I have to calculate the average from 1st January to 31st January, then again 1th Feb. to 26th Feb. and so on.....Below is the program to read the values. and also attaching the data sets

%% New Program for Wind Vector data=netcdf.open('uwnd.sig995.2014.nc','NC_NOWRITE'); data1=netcdf.open('vwnd.sig995.2014.nc','NC_NOWRITE');

ug=netcdf.getVar(data,3,[0 0 0],[144 73 1],'double'); vg=netcdf.getVar(data1,3,[0 0 0],[144 73 1],'double'); lat1 = netcdf.getVar(data,0,0,73); lon1 = netcdf.getVar(data,1,0,144); ind = find(ug==9999); ug(ind) = NaN; vg(ind) = NaN; % end

[Lat, Lon] = meshgrid ( lat1, lon1 ); ws=sqrt(ug.^2+vg.^2);

% figure magnification

m_proj('Mercator','lon',[65 100],'lat',[5 40],'rect','on'); % Making projection % m_pcolor(Lon,Lat,ws); m_coast('patch',[.6 1 .6],'edgecolor','none'); m_grid('tickdir','out','yaxislocation','right',... 'xaxislocation','top','xlabeldir','end','ticklen',.02);

   hold on
 m_contourf(Lon,Lat,ws)
% m_plot(Lon,Lat,'color','k','linewidth',2.5);
m_quiver(Lon,Lat,ug,vg,50,'k');
hold off

You can use downsample_ts. Syntax would be

ug_monthly = downsample_ts(ug,t,'monthly','mean');
