Error in untitled (line 52)
u1 = ncread(fullfile(filename,'uo'),[1 1 nz 1],[length(lon) length(lat) 1 ntime]);
for yi=1:nyear
ny=ystart+yi-1
filename=fullfile(fp,['June' num2str(ny) '.nc']);
u1 = ncread(fullfile(filename,'uo'),[1 1 nz 1],[length(lon) length(lat) 1 ntime]);
v1 = ncread(fullfile(filename,'uo'),[1 1 nz 1],[length(lon) length(lat) 1 ntime])
% if you want monthly averages, do this
% note this will end up a different dimension if you're extracting
% multiple layers
% might want to predefine these matrices depending on what you want
% https://uk.mathworks.com/help/matlab/ref/mean.html
u2(:,:,yi)=mean(u1,[4]); whos u2
v2(:,:,yi)=mean(v1,[4]);
end
% then take the mean to get the mean over all the years, for one depth
% layer only, remember
u3=mean(u2,[3]); %taking the mean over the third dimension
v3=mean(u2,[3]);
% calculate the magnitude of the vel and plot
uv4=sqrt(u3.^2+v3.^2);
close all, pcolor(LON,LAT,uv4.'), shading flat, colorbar

u1 = ncread(filename,'uo',[1 1 nz 1],[length(lon) length(lat) 1 ntime]);
v1 = ncread(filename,'uo',[1 1 nz 1],[length(lon) length(lat) 1 ntime]);

See the above question / answer which discusses similar issue, I think its related with Version and /or file limit contents

I altered my data, as it was a typo and teh variables should have been uo and vo for u1 and v1, but I get the same error.
